[svn-r4015] Purpose:
Code cleanup
Description:
Several system functions don't have prototypes on Linux machines with our
current compile flags.
Solution:
Add _POSIX_SOURCE and _BSD_SOURCE macros to the compile line when compiling
on Linux machines, to pick up missing prototypes.
Platforms tested:
Linux (eirene), FreeBSD 4.3 (hawkwind)
