Hey,

sometimes, when I run a script that executes the usual commands to configure 
the autotools (aclocal, autoconf, etc...), or when I run autoreconf -f -i, I 
get the error "possibly undefined macro" for AC_DEFINE. Today, it with 
AC_CHECK_LIBS

The code that is related to that amcro is:

AC_CHECK_FUNCS([fnmatch],
    [res="yes"],
    [res="no"]
)

if test "x$res" = "xno" ; then
    AC_CHECK_LIBS([fnmatch],
       [fnmatch iberty],
       [res="yes"],
       [res="no"]
    )
    if test "x${}" = "xno" ; then
       AC_MSG_ERROR([Cannot find fnmatch() in neither libc nor libfnmatch, nor 
libiberty])
    fi
fi

(note: iberty is for mingw)

But, when I run myself all the commands of my script, in the same order, in the 
terminal, that is:

aclocal  -I m4
autoheader
autoconf
libtoolize --copy --automake
automake --add-missing --copy --gnu

then, everything is fine, no error...

Does someone know what the problem is ?

thank you

Vincent Torri
