Hi does the cygwin32 distribution lack the header files tcp.h and udp.h (needed by some programs I'd like to compile) or are their defines like those of malloc.h contained by some other header file? Thanks for any hints. Regards, G.Heini - For help on using this list (especially unsubscribing), send a message to "gnu-win32-request@cygnus.com" with one line of text: "help".
