For the simplest possible configure.ac:
AC_INIT
AC_PROG_LEX
if test -z "$LEXLIB"; then
AC_MSG_ERROR(no lexlib)
fi
We get:
checking for gcc... no
checking for cc... cc
checking for C compiler default output file name... a.out
checking whether the C compiler works... yes
checking whether we are cross compiling... no
checking for suffix of executables...
checking for suffix of object files... o
checking whether we are using the GNU C compiler... no
checking whether cc accepts -g... yes
checking for cc option to accept ISO C89... none needed
checking for flex... flex
checking lex output file root... lex.yy
checking lex library... none needed
checking whether yytext is a pointer... no
configure: error: no lexlib
Because (from config.log):
cc-1042 cc: ERROR File = conftest.l, Line = 6
The types of operands "char *" and "int" are incompatible.
{ yyless (input () != 0); }

1 error detected in the compilation of "conftest.c".

I think we need to patch programs.m4 to change thusly:
