Portability
-----------
FIXME C99, POSIX
Code for IEEE Std 1003.1-2001 (POSIX.1-2001) with the X/Open System
Interfaces Extension. This standard includes ISO/IEC 9899:1999 (C99)
by reference.
Some systems may have flaws that require work-arounds. Use Autoconf
to detect the flaws, and isolate the system-specific code, e.g. by
providing a replacement function when the system's function is flawed.
Keeping the Windows build working may require extending src/lib/w32/.
Keep the client as portable as practical. In particular, stick to
C89.
