Description
The change https://codereview.qt-project.org/#/c/157817/ is not OK on MSYS2.
While MSYS2 uses GCC (details below), it's still a Windows platform and the patch results in detecting wrong paths for QMAKE_DEFAULT_LIBDIRS and/or QMAKE_DEFAULT_INCDIRS.
qmake builds correctly, but every time it is run, it prints "unable to access the specified path". Multiple times if creating a Makefile.
Conditioning the gcc block like this "!win32:gcc {" fixes the error, so basically the patch is a regression that wasn't there on 5.6.x.
When applying patches like this, please try to consider also the MSYS2 case, cause a few people relies on it (and cause it took me a week to figure this out...). Thanks
