#415 CRT is incompatible with -Wl,--disable-auto-import

[Noah Misch]

The following test procedure is based on a fresh mingw-w64-install.exe
installation, started with the "Run terminal" start menu link.

C:\Program Files\mingw-w64\x86_64-4.9.1-posix-seh-rt_v3-rev0>echo off

I can also reproduce it with mingw64-x86_64-runtime-3.1.0-1 currently shipping
with Cygwin's setup-x86.exe.

This seems liable to be related to [#335], [0eb0c0] and [532e1c].

Thanks,

Can you please try this patch?

Thanks.

That patch fixes my trivial test case. This bug report originated from an
attempt to build PostgreSQL 9.4. With this patch, PostgreSQL builds and
passes "make check". Thanks for the rapid help.

Thanks, applied to v3.x and master, will update Cygwin release soon.
