Ascent Win32/64 Libraries Distribution [help]

alright so when i try and follow the Ascent Win32/64 Libraries Distribution guide i keep getting a error when trying to compile zlib and PCRE libraries.
i run VC90-solution.sln under the Sources folder, change the build to release win32 and build solution. and i keep getting this..

c:\users\Gary\desktop\ascent-windows-libraries\ascent-windows-libraries\sources\pcre\pcre_internal.h(73) : fatal error C1083: Cannot open include file: 'ctype.h': No such file or directory

c:\users\Gary\desktop\ascent-windows-libraries\ascent-windows-libraries\sources\zlib\zutil.h(21) : fatal error C1083: Cannot open include file: 'stddef.h': No such file or directory

so 2 failed... any ideas? and I'm using vista, its been alot of my problems in the past so i dono if that would change anything.

btw i dono shit about c++ >_> so im sure thats the main problem

could someone help me on this?
