Subject: [PATCH] Use _W64 to detect MinGW W64-32 instead of _FILE_OFFSET_BITS
f731ee
f731ee
In 94cee4a4c201bb506377b2c26e072eee8cb19d6f I overlooked that config.h
f731ee
unconditionally sets _FILE_OFFSET_BITS, so it cannot be used to detect
f731ee
MinGW W64 environment. It looks like Emacs folks already found
f731ee
solution; instead of _FILE_OFFSET_BITS use _W64 as suggested in
f731ee
