AIX 4.3: All functions available.
IRIX 5.3: All functions available.
SunOS 5.5: All functions available.

Linux Red Hat 6.1
-----------------

getcontext/setcontext/swapcontext/makecontext are all defined in
<ucontext.h>, although there are man pages only for getcontext and
setcontext and the linker says:

/tmp/ccfrjprH.o: In function `main':
/tmp/ccfrjprH.o(.text+0x13): warning: getcontext is not implemented and will always fail
/tmp/ccfrjprH.o(.text+0xe): warning: setcontext is not implemented and will always fail
/tmp/ccfrjprH.o(.text+0x4): warning: makecontext is not implemented and will always fail
/tmp/ccfrjprH.o(.text+0x9): warning: swapcontext is not implemented and will always fail

In other words, functions not available (yet?).

Hope that helps.
