I need some .h files, any ideas where to get them?

[esmerelda]

Hi.

I'm compiling my MUD engine, which is C based, in MSVC++, but I need some header files in order to complete it. I've got some of them from packages used in solaris, but I don't know where to get the rest (listed below)

Files needed:
unistd.h
sys\time.h
zlib.h (found this in the solaris zlib package...)
zconf.h (found this in the solaris zlib package too...)

Any Ideas?

Thanks.

EDIT: P.S. I'm running Windows XP, but the fact I'm using MSVC++ makes that obvious. Also, I'm using version 6. Just thought it might make a difference, not sure tho... Thanks...
