dnl Process this file with Autoconf to produce a configure script for TeX.

dnl We don't use (for example) tex/tex.web because people who only want
dnl to build part of the distribution may not have any given program.
dnl Even web2c.c isn't guaranteed, but then nothing is ...

AC_CONFIG_HEADER(lib/c-auto.h)
dnl Don't complain when common.ac uses AC_CONFIG_HEADER.

AC_PROG_YACC
AC_PROG_LEX
AC_PROG_LN_S
AC_TYPE_SIGNAL
dnl These tests prevent reliable cross-compilation. Sigh.
AC_C_CHAR_UNSIGNED
AC_LONG_64_BITS
AC_C_BIGENDIAN
dnl Must do this last, as the addition to DEFS in Autoconf 1.3 confuses
dnl the compiler.
AC_DECL_YYTEXT
dnl Check if lib/c-auto.h.in defines a preprocessor symbol.
