In lesstif-0.92.6 is some bugs in configure.in and acinclude.m4, which
gives unexpected values for CFLAGS. My system is Redhat linux 6.1, and
my compiler i gcc. I ran the configure script and got
CFLAGS = -g -O2 -I/usr/X11R6/include -g, but what i expected was
CFLAGS = -g -Wall. The errors i found in configure.in is:
1) The check for compileflags should be after AC_PROG_CC. If not you
can't know if you is using gcc.
2) When you saves CFLAGS you uses an variable lt_save_CFLAGS, but the
same variable is used in several of the macros in acinclude.m4 -
thus making it impossible to restore CFLAGS again.
In acinclude.m4 is there some errors in LT_HAVE_GETHOSTNAME:
1) AC_TRY_LINK does only take 4 arguments.
2) The lines where CFLAGS, CPPFLAGS and LIBS get restored is
misplaced. If the macro get its value from the cache the variables
is restored without beeing saved first.
AM_FUNC_VOID_SPRINTF is also broken, as it dumps core on my
system. The sprintf function is called with only one argument, which
is wrong.
I have made a new version of AM_PROG_CC_STDC, which may give the right
compile-flags for SCO-unix.
New version of AM_PROG_CC_STDC:
AC_DEFUN(LT_PROG_CC_STDC,
[AC_REQUIRE([AC_PROG_CC])
AC_BEFORE([$0], [AC_C_INLINE])
AC_BEFORE([$0], [AC_C_CONST])
dnl Force this before AC_PROG_CPP. Some cpp's, eg on HPUX, require
dnl a magic option to avoid problems with ANSI preprocessor commands
dnl like #elif.
dnl FIXME: can't do this because then AC_AIX won't work due to a
dnl circular dependency.
dnl AC_BEFORE([$0], [AC_PROG_CPP])
