8.0.0b1 cygwin problems

I haven't tested this with mingw or MSVC but the default cygwin layout
needs the attached header changes.

pending problems:

src/timezone has a configure problem
pgtz.c:105:2: #error No way to determine TZ? Can this happen?

PGAC_VAR_INT_TIMEZONE return no for cygwin, but our time.h has this:
   extern __IMPORT time_t _timezone;
which is from newlib.
I truly mistrust PGAC_VAR_INT_TIMEZONE in config/c-library.m4

Right now the gcc-3.4.1 build for cygwin is in experimental status, we
will see what will change then. So far we only have gcc-3.3.
