- Updated the scanf() test to check if the fixes for the scanf() family
regarding '%x' and leading zeroes in strings to be parsed are really
working.

c.lib 1.179 (22.10.2004)

- The scanf() family no longer assumes that a leading '0' indicates that the
following digits form an octal number if the conversion type has been
specified as already '%x' already.

This commit was manufactured by cvs2svn to create tag 'V1_178'.

c.lib 1.178 (7.10.2004)

- The OS4 version had floating point math support code enabled in all
libraries and not just "libm.a". Fixed.

Fixes for compiler errors with soft-float

- Floating point support code generation was enabled for the entire PowerPC
library, and not just for "libm.a". Fixed.

- Updated the release notes file.

- 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.
