============
VERSION 41.4
============
Integrated patches from Hans Verkuil that fix CTRL-C handling, fix another
signal bug, fix problem with "rm -f", prepare for proper timezone handling,
and remove '@' hack in argument parsing.
Applied patch from Kamil Iskra to avoid incompatibility between ixemul
and the popular KingCON 1.3. This is KingCON's fault because it makes
invalid assumptions about the nature of reply port contained in "dp_Port"
of packets sent to it. Also applied patch (duplicated in Han's patches)
to crt0.c that fixes bug where the revision requester was not working
properly if the current revision is 0.
Applied patch from Rask Lambertsen (duplicated in Han's patches) that makes
ixemul.library open "CONSOLE:" instead of "*".
Added implementation from Kriton Kyrimis for srand48, seed48, lcong48,
lrand48, nrand48, mrand48, jrand48, drand48, and erand48.
Added "#include <sys/types.h>" to <dirent.h> to be more compatible
with most current systems that do this inclusion for you. This change
should be backwards compatible with code that does the inclusion
explicitly. Suggested by Lars Hecking.
Changed prototype in <unistd.h> for getpgrp() to take a pid_t argument,
which matches the implementation in library/getcrap.c. Suggested by
Lars Hecking.
Made change to <math-68881.h> in pow() so that if x<0 the code does
log(-x) rather than log(x). Suggested by Thomas Radtke and implemented
by Lars Hecking.
Disable definitions of F_GETLK, F_SETLK, F_SETLKW, F_RDLCK, F_UNLCK, and
F_WRLCK in <fcntl.h> since they are unimplemented and thus might have misled
autoconfiguration schemes into thinking they were available. Also fix
ixtrace.c so it will still compile without these defined. Suggested by
Robert Ramiega.
Integrated patch from joop van de wege (duplicated in Han's patches) for
setting up fpu on 68060.
============
VERSION 41.3
============
Updated DBL_MIN and DBL_MAX in float.h to include one additional digit
of precision. Enclose negative constants in parens to avoid unexpected
conversion to subtraction via cpp macros.
Applied patch from Hans Verkuil to fix serious bug in signal handling,
to reset all signal handlers after an execve, except for those which are
being ignored (SIG_IGN).
Applied patch from joop van de wege to trap.s to set 68881 rounding mode
back to truncation instead of "round to nearest", as required by the
ANSI C standard which specifies truncation.
Integrated ixtrace into source tree and arranged for it to be built and
installed.
============
VERSION 41.2
============
Added "#include <sys/types.h>" to <sys/stat.h> to be more compatible
with most current systems that do this inclusion for you. This change
should be backwards compatible with code that does the inclusion
explicitly.
Changed version string to be style guide compliant. Also arranged that
version.o gets linked in, since it has the $VER: string and is otherwise
unreferenced by any ixemul.library code.
Merged patches from Hans Verkuil to fix execve environment passing,
always open the console for stderr if no other file handle is provided,
move AmigaDOS style filename matching into glob(), and fix a small problem
with "open(NULL,...) that caused enforcer hits.
============
VERSION 41.1
============
A 68040 version of the library with soft floating point is now built,
since there are apparently systems that use the versions of the 68040
without FPUs.
Fixed crt0 files to use "jra _ENTRY" as first instruction rather than
"jmp pc@(_ENTRY)" which was getting assembled by gas 2.5.2 as a 68020+
instruction. Note "jmp pc@(_ENTRY:W)" seems to generate the 68000
instruction but a bad jump offset. Added corresponding change to
execve.c to recognize ixemul using executables with this change.
Fixed cpu.h, machdep.c, trap.s to avoid pc relative assembly instruction
that was getting compiled as 68020+ instruction and causing crashes on
68000 machines.
Fixed numerous files that did "#include" of "DEFS.H" rather than "defs.h".
This is an innocuous bug on the Amiga, which is case independent, but
it kills cross compilations.
============
VERSION 41.0
============
No significant changes since the 40.6 beta release other than the
mechanism (and macros) for building debug versions has been cleaned
up and the version number has been bumped to 41.0.
Did include the cat'able man pages back in the source tree, but no
work has been done yet to track down the sources for the man pages
and arrange for them to be properly integrated into the tree and
have the cat'able versions generated from those sources.
============
VERSION 40.6
============
Many bugs have been fixed since the 40.4 release, including a serious
one that was causing memory corruption and many enforcer or mungwall
hits.
Network support has been reintegrated into the library, however it is
still mostly untested. In particular, many functions are only
available for static linking from the libnet.a library. By the next
release, it is expected that libnet.a will be incorporated in libc.a.
Work is underway to merge the best features from at least two
different strains of the ixemul library. Many more changes are
expected by the 41.0 release.
An environment variable called "IXSTACK" is now used to control the
stack size of programs started by system(). If the current stack is
smaller than the value in IXSTACK, the stack is raised to the value
specified in IXSTACK. So IXSTACK is a minimum value.
Automatic stack checking, with a requestor if the stack overflows, is
available for executables compiled with a version of gcc that supports
the -mstackcheck option. This also requires linking with new crt0 and
libc.a.
Automatic stack extension as necessary is available for executables
compiled with a version of gcc that supports the -mstackextend option.
This also requires linking with new crt0 and libc.a.
