clib2 Code

- 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.

- Added C99 checks to "complex_headers.h".

- No longer uses a local copysign() function in "math_kernel_scalbn.c".

- Fixed an assignment which actually came out as a comparison in "stdio_vfscanf.c".

- Added C99 checks to "complex_headers.h".

- No longer uses a local copysign() function in "math_kernel_scalbn.c".

- Fixed an assignment which actually came out as a comparison in "stdio_vfscanf.c".

- Getting ready for the 1.192 release.

- Floating point output in hexadecimal notation can now show a sign
in front of the hex prefix string.

- fflush() no longer calls flockfile()/funlockfile() with a NULL parameter.

- Removed the old isinf() and isnan() functions.
