clib2 Code

This commit was manufactured by cvs2svn to create tag 'V1_169'.

c.lib 1.169 (8.8.2004)

- Since the 'long double' data type is not really supported by the GCC
versions we use (and not supported by SAS/C either) building the
library with support code for it is now a configurable option. Unless
enabled, 'long double' is now treated like 'double'.

- Reworked the HUGE_VAL definition which previously would default to
Infinity. The new code properly defines this to the largest
representable floating point number. The 'great' thing about the
HUGE_VAL definition in this library is that it's a reference to
a binary constant initialized by the library startup code. So any
application checking for HUGE_VAL merely needs to be relinked
rather than recompiled.

- Moved the isascii() definition behind the "The following is not part of the
ISO 'C' (1994) standard." warning.

This commit was manufactured by cvs2svn to create tag 'V1_168'.

c.lib 1.168 (7.8.2004)

- Ditched __is_infinity() and __is_not_a_number(), brought them back
as isinf() and isnan().

- Updated code and header files to state exactly which ISO 'C' version
is meant by the "The following is not part of the ISO 'C' standard."
warning.

- Integrated rint() and rintf().

- Ditched __is_infinity() and __is_not_a_number(), brought them back
as isinf() and isnan().

- Updated code and header files to state exactly which ISO 'C' version
is meant by the "The following is not part of the ISO 'C' standard."
warning.

- Integrated rint() and rintf().

Implements the functions rint and rintf (float version).
The rint function rounds the argument to the integral value. Used for
example in the Ogg Vorbis libraries.

- Fixed the smakefile so that the library builds properly.

- Moved the test program smakefile portions into a separate file.

- Added comments explaining how to set up the header files.

- Added notes on building the library

- Added a build smakefile, which is based upon the original smakefile used for building
the library and the test code.
