[Win32] 5.27.11 fails to build with MinGW

Hi,

I'm using gcc version 7.2.0 (i686-posix-dwarf-rev1, Built by MinGW-W64 
project).
And I'm building with gmake on Windows 7.

There was no problem building 5.27.10 with these tools, but with 5.27.11 
(and using the very same tools) XS\APItest\APItest.dll  fails to build.

Firstly, there's some deprecation warnings during the compilation of 
APItest.c, followed soon after by linking failures when the attempt to build 
the dll is made.
(I don't know whether those deprecation warnings were also present in the 
5.27.10 build.)

Same result when I build using gcc version 7.2.0 (x86_64-posix-seh-rev1, 
Built by MinGW-W64 project).
