- MinGW doesn't have struct timespec, so udf_time.c doesn't compile (changes lib/udf/udf_time.c, configure.ac, config.h.in) - The configure test for bitfield ordering uses AC_TRY_RUN and thus doesn't work when cross-compiling; use sneakiness to try and determine it at compile time, falling back to the existing runtime check if the sneakiness doesn't work (changes configure.ac; tested on x86_64-linux-gnu and i586-mingw32 which are bf_lsbf=1, plus sparc64-linux-gnu which is bf_lsbf=0) - The configure test for "extern long timezone" needlessly uses AC_TRY_RUN when in fact AC_LINK_IFELSE is all we need to know, and that latter works when cross-compiling (changes configure.ac) - MinGW sys/stat.h doesn't have the *GRP or *OTH macros, nor S_IFLNK or S_IFSOCK, nor S_ISUID etc (changes lib/udf/udf.c and lib/iso9660/xa.c) - MinGW doesn't have <sys/wait.h>, so even the header-inclusion bit of the Linux driver doesn't compile unless it's moved inside the "ifdef HAVE_LINUX_CDROM" (changes lib/driver/gnu_linux.c) - Because the man pages cd-info.1 etc depend on the binaries themselves (for help2man reasons), the configure options --without-cd-info etc don't actually stop them being compiled. Fixed by only depending on man pages for programs that are actually built, which also stops the installation of man pages of programs which aren't themselves installed (changes src/Makefile.am)
