Hello,
I have acquired both MinGW and MinGW64 versions of gcc. Here are the gcc -v and CCHOME from makefile.mk for each:
32 bit:
CCHOME *= C:\MinGW
C:\Users\dcollins>C:\MinGW\bin\gcc -v
Using built-in specs.
COLLECT_GCC=C:\MinGW\bin\gcc
COLLECT_LTO_WRAPPER=c:/mingw/bin/../libexec/gcc/mingw32/4.9.3/lto-wrapper.exe
Target: mingw32
Configured with: ../src/gcc-4.9.3/configure --build=x86_64-pc-linux-gnu --host=mingw32 --prefix=/mingw --disable-win32-registry --target=mingw32 --with-arch=i586 --enable-languages=c,c++,objc,obj-c++,fortran,ada --enable-static --enable-shared --enable-threads --with-dwarf2 --disable-sjlj-exceptions --enable-version-specific-runtime-libs --enable-libstdcxx-debug --with-tune=generic --enable-nls
Thread model: win32
gcc version 4.9.3 (GCC)
64 bit:
CCHOME *= C:\MinGW\mingw64 # Changed to support install directory
C:\Users\dcollins>C:\mingw-w64\i686-4.9.3\mingw32\bin\gcc -v
Using built-in specs.

Thread model: posix
gcc version 4.9.3 (i686-posix-dwarf-rev1, Built by MinGW-W64 project)
Compiling the 32 bit version fails quite early:
gcc -c -I.\include -I. -I.. -DWIN32 -DWIN64 -DCONSERVATIVE -DPERLDLL -DPERL_CORE -s -O2 -fwrapv -fno-strict-aliasing -DPERL_EXTERNAL_GLOB -DPERL_IS_MINIPERL -omini\toke.o ..\toke.c
In file included from ..\perl.h:3205:0,
from ..\toke.c:40:
./win32.h:363:13: error: conflicting types for 'mkstemp'
extern int mkstemp(const char *path);
^
In file included from ..\perl.h:781:0,
from ..\toke.c:40:
c:\mingw\include\stdlib.h:796:30: note: previous definition of 'mkstemp' was here
__cdecl __MINGW_NOTHROW int mkstemp (char *__filename_template)
^
The 64 bit version uses this command, which compiles successfully:
gcc -c -I.\include -I. -I.. -DWIN32 -DWIN64 -DCONSERVATIVE -DPERLDLL -DPERL_CORE -s -O2 -fwrapv -fno-strict-aliasing -DPERL_EXTERNAL_GLOB -DPERL_IS_MINIPERL -omini\toke.o ..\toke.c
