C header files

I am trying to compile netcat on windows XP.
It says I need some header files, but I assume that I would need the library files as well...

Any good sources on reliable header files?
Error E2209 PING.C 24: Unable to open include file 'std.h'
Error E2209 PING.C 25: Unable to open include file 'gppconio.h'
Error E2209 PING.C 26: Unable to open include file 'pc.h'
Error E2209 c:\Borland\Bcc55\include\socket.h 5: Unable to open include file 'sy
s\uio.h'
Error E2209 c:\Borland\Bcc55\include\socket.h 6: Unable to open include file 'sy
s\time.h'
Error E2139 c:\Borland\Bcc55\include\wattcp.h 93: Declaration missing ;

OP here.
I decided to decompile the binary with ollydbg and just write a couple encryption routines in asm...

BUT I WOULDNT MIND KNOWING OF A HEADER SEARCH ENGINE, like "Looking for packet.h" OH THATS FUCKING WINPCAP FOR WINDOWS or LIBPCAP for LINUX
