Winsock types all buffers as pchar (char *), modern POSIX does it the ANSI
C way with pointer (void *). If the pointer overloaded version doesn't exist,
a "pointer" will be passed to the "var" version. (bug 3142).
So if there are var/const versions:
- To keep ported unix code working, there must be "pointer" variants (ANSI)
- To keep Delphi/ported C Winsock code working there must be pchar variants
(K&R)
IOW, there _must_ be 3 versions then: var/const, pchar and pointer}
