[Expat-bugs] Little bug fix in expat-1.95.6

The supplied "conftools/expat.m4" sets
EXPAT_CFLAGS="-I$with_expat/include"
CFLAGS="$CFLAGS $EXPAT_CFLAGS"
before
AC_CHECK_HEADERS(expat.h, , expat_found=no)
on some systems (for example "i686-pc-linux-gnu", "gcc 2.96") it may be
broken (the bug exploits during "checking expat.h presence" where
preprocessor is used and CFLAGS {-I/mypath/expat} are not passed to
command).
The attached version addresses this little bug.
Regards
Christian

dnl Check if --with-expat[=PREFIX] is specified and
dnl Expat >= 1.95.0 is installed in the system.
dnl If yes, substitute EXPAT_CPPFLAGS, EXPAT_LIBS with regard to
dnl the specified PREFIX and set with_expat to PREFIX, or 'yes' if PREFIX
dnl has not been specified. Also HAVE_LIBEXPAT, HAVE_EXPAT_H are defined.
dnl If --with-expat has not been specified, set with_expat to 'no'.
dnl In addition, an Automake conditional EXPAT_INSTALLED is set accordingly.
dnl This is necessary to adapt a whole lot of packages that have expat
dnl bundled as a static library.
