clib2 Code

- The record locking code in fcntl() is no longer part of the
regular libc.a, but only of libunix.a.

- Changed the definition of the D_S() macro to cast the pointer
address to an unsigned 32 bit integer.

- For %C strtime() should return the century number, not the
year number mod 100.

- Moved the IExec initialization in "simple_sprintf.c".

- Forgot to update the .cvsignore file to ignore the simple_sprintf test
program.

- Added a simple test for sprintf() which does not use any of the
normal library startup code.

- Documented __strip_double_slash() and plugged in a memmove()
in place of the copying loop.

- Modified __translate_unix_to_amiga_path_name() and
__translate_amiga_to_unix_path_name() to not to call strlen()
on the results of __strip_double_slash().

- Added %D, %e, %F, %g, %G and %h for strftime(); repaired %I.

- Added tests for inf/nan.

- fpclassify() now returns FP_ZERO both for 0 and -0.

- nan() and nanf() now return quiet NaNs.

- Added internal __inf() and __inff() functions.

- strtof() now calls nanf() and __inff(), respectively, to produce
the special floating point values for nan/inf/infinity.

- strtod() now calls nan() and __inf(), respectively, to produce
the special floating point values for nan/inf/infinity.

- The scanf() family now calls nan() and __inf(), respectively, to
produce the special floating point values for nan/inf/infinity.

- Enabled the C99 language option.
