Failure in apr_i686-w64-mingw32.static.posix.dw2:
I see the same for apr with i686-w64-mingw32.static.posix.dw2, it's most likely related to posix as i686-w64-mingw32.static.dw2 succeeds.
allow non-default exception handling targets
Makefile: add [POSIX | WIN32]_THREADS variable
apr: fix posix build and use SOURCE_DIR etc.
libmysqlclient: fix redefinition of pthreads functions
libmysqlclient fixed - causes downstream breakage of gdal.
For i686-w64-mingw32.static.dw2 and x86_64-w64-mingw32.shared.win32.sjlj all packages including plugins apps, luarocks and go were built.
