[PATCH] poll: undef NOGDI

From: Marat Radchenko
Subject: [PATCH] poll: undef NOGDI
Date: Thu, 18 Sep 2014 16:53:37 +0400

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 <address@hidden>

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.
