Generator can't find any of the structs of methods from time.h

[Mbucari]

I've tested both ffmpeg v6.0.1 and v7.1.1 with the following command:

./project_generate --disable-swscale --disable-avdevice --disable-doc --disable-v4l2-m2m --disable-vaapi --disable-vdpau --disable-network --disable-libxcb --disable-libxcb-xfixes --disable-libxcb-shape --disable-zlib --disable-iconv --disable-alsa --disable-shared --enable-static --disable-doc --disable-symver --disable-programs --disable-debug --enable-pic --disable-everything --enable-decoder=aac --enable-decoder=pcm_f32le --enable-decoder=pcm_s16le --enable-encoder=aac --enable-encoder=pcm_f32le --enable-encoder=pcm_s16le --enable-parser=aac --enable-demuxer=aac --enable-demuxer=pcm_f32le --enable-demuxer=pcm_s16le --enable-muxer=pcm_f32le --enable-muxer=pcm_s16le --enable-filter=aresample --enable-filter=asetnsamples --enable-muxer=mov --enable-muxer=mp4 --enable-demuxer=mov

And here's the error from the ffvs_log.txt file:

I tried adding a copy of the tm and timespec structs to ffmpeg/libavutil/time.internal.h and adding #include "libavutil/time_internal.h" to w32pthreads.h, and that gets the generator past w32pthreads.h, but then it fails at time_internal.h with a type re-definition error.

It seems like the generator may be confusing the c-lib time.h with /libavutil/time.h. I worked around this by creating a copy of the time.h file in the windows SDK named time_win.h, then replacing the #include <time.h> with #include <time_win.h> in /libavutil/random_seed.c, /libavutil/time_internal.h, and /compat/w32pthreads.h.
