Howto build libpq.dll using VC2003 and ENABLE_THREAD_SAFETY=1

Building without ENABLE_THREAD_SAFETY=1 works fine, but when
i add this option to the win32.mak some compiler error occur.

d:\postgresql-8.0.3\src\interfaces\libpq\libpq-int.h(481) : error
C2143: syntax error : missing ')' before '*'
d:\postgresql-8.0.3\src\interfaces\libpq\libpq-int.h(481) : error
C2143: syntax error : missing '{' before '*'
d:\\postgresql-8.0.3\src\interfaces\libpq\libpq-int.h(481) : error
C2371: 'bool' : redefinition; different basic types
d:\postgresql-8.0.3\src\include\c.h(174) : see
declaration of 'bool'
d:\postgresql-8.0.3\src\interfaces\libpq\libpq-int.h(481) : error
C2143: syntax error : missing ';' before '*'
d:\postgresql-8.0.3\src\interfaces\libpq\libpq-int.h(481) : error
C2059: syntax error : ')'
...

It looks like sigset_t is not defined.
Please help.

Pit :-)

I beleive there is a patch floating around for
libpq-threadsafe-on-win32, but it hasn't been applied yet. Check the
archives, IIRC it was by Dave Page.
