clib2 Code

- Fixed the stack swapping function which, for reasons unknown, ceased to work.

- Updated the .cvsignore file to ignore the _rev.i and _rev.s files.

- The start time used by clock() is now initialized by a constructor
function.

- NOTE THAT ALL THE CHANGES WITH REGARD TO USE OF DESTRUCTOR AND
CONSTRUCTOR FUNCTIONS REQUIRE A COMPLETE REBUILD OF THE LIBRARY! IF
YOU DO NOT DO THIS, THE CONSTRUCTOR/DESTRUCTOR FUNCTIONS MAY NOT
GET CALLED.

- The socket exit code now calls the common stdio function which
flushes and shuts down all buffered and unbuffered files.

- Reversed the 'unsigned long' -> 'ULONG' change in the constructor
handling code. It is not necessary.

- Added an OS4 specific build makefile.

- Modified the socket functions which now take parameters to constant
pointers.

- Fixed fabs() for PowerPC soft-float support; previously, the function
definitions would clash.

- unistd_timer.c was missing...

c.lib 1.177 (29.9.2004)

- The stdio cleanup function is now a destructor.

- The stack extension cleanup function is now a destructor.

- The code that cleans up after the program's current directory
