pg_config.h.win32

Hi

I examined multibyte psql.exe and libpq.dll Yesterday
according to the bug report from Hiroshi Saito.
At first the compilation didn't work at all and I found
the following in src/win32.mak though it's irrelevant to
the bug report.

ALL:
cd include
if not exist pg_config.h copy pg_config.h.win32 pg_config.h

Currently I'm working under cygwin environment mainly and
the above script doesn't work well after the configure of
cygwin (un??)fortunately. It's pretty painful and risky to
change pg_config.h.win32 and the original pg_config.h.
How about including pg_config.h.win32 in pg_config.h e.g.

#ifdef WIN32
#include "pg_config.h.win32"
#else
.
.

?

Comments ?
