win_bison can't find data directory unless it's in the current directory

[nirbheek]

Starting with 2.5.19, if the data/ directory isn't in the current directory, running win_bison gives the following error: data/m4sugar/m4sugar.m4: cannot open: No such file or directory

Looking at the git history, this broke while merging the upstream changes. bison/src/main.c doesn't use get_local_pkgdatadir() anymore, which had been patched to use get_app_path() from common/misc/app_path.c. Instead, the datadir is fetched by calling pkgdatadir() in bison/src/files.c. So, that function needs to be changed to call get_app_path() and return that path.

Thank you for discovering this bug. Going to fix it soon.

I was able to hit it too when building Mesa3D with MSVC.

Try this binary. If it works I'll publish it.
win_flex_bison-2.5.20.zip

I tested it and it works great, thanks!

It worked for me too.
