Subject: configure.ac: automatically add include/mingw/ headers
X-Git-Tag: v1.46.6~85
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b3d180e2057ebb144ab7e52c0153eb0f000c497a;p=thirdparty%2Fe2fsprogs.git

configure.ac: automatically add include/mingw/ headers

Since the include/mingw/ directory needs to be on the include path when
building for Windows with MinGW, add it to INCLUDES automatically, and
AC_DEFINE the corresponding HAVE_*_H constants.
