Hello Paul, I have seen a test failure when cross-compiling GnuTLS to mingw32 and running the testsuites with Wine[1]. It looks like the library mis-calculates timeout value for DTLS, because of a confusion in time_t size detection.
The configure output shows some clue: checking for 64-bit time_t... no checking for 64-bit time_t with _TIME_BITS=64... no configure: WARNING: This package requires a 64-bit 'time_t' type if there is any way to access timestamps outside the year range 1901-2038 on your platform. Perhaps you should configure with 'CPPFLAGS="-m64" LDFLAGS="-m64"'? checking whether time_t is signed... yes checking size of time_t... 8 where I observe: - AC_CHECK_SIZEOF reports time_t is 64-bit, as gl_YEAR2038_EARLY sets __MINGW_USE_VC2005_COMPAT - gl_YEAR2038_BODY is called before gl_YEAR2038_EARLY as a dependency of AC_SYS_LARGEFILE - Therefore checks in gl_YEAR2038_BODY are not affected by __MINGW_USE_VC2005_COMPAT and report that time_t is NOT 64-bit I guess a simple solution would be to swap the order of gl_YEAR2038_EARLY and AC_SYS_LARGEFILE in modules/largefile, as with the attached patch. This doesn't fully resolve the issue with DTLS tests as mentioned, and I suspect there might be some other confusions. Any suggestions would be appreciated.
