On MinGW-W64, MsgWaitForMultipleObjects is guarded with #ifndef NOGDI. -DNOGDI=1 prevents inclusion of tons of Windows headers, especially wingdi.h with weird #define ERROR 0 that has high chances to conflict with internal software defines. So, just #undef NOGDI.
MinGW-W64 bug: http://sourceforge.net/p/mingw-w64/bugs/397/ When it is fixed, this commit can be reverted. Signed-off-by: Marat Radchenko <ma...@slonopotamus.org> --- This issue was encountered during adoption [1] of git for MinGW-W64. Possibly there is a better workaround I'm unaware of. Please, use 'reply to all', I'm not subscribed to gnulib ML.
