- The printf() family now produces no output at all for %e, %f and %g if the
floating point support code is disabled. Previously, a minimum field width
specification could take effect, printing a series of 0 or blank space
characters where no output should have been produced.

- The OS4 version had floating point math support code enabled in all
libraries and not just "libm.a". Fixed.
git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@14750 87f5fb63-7c3d-0410-a384-fd976d0f7a62
- <stdarg.h> now tries to use the compiler supplied, machine specific
<stdarg.h> file and also includes the OS4-specifc <sys/amigaos-va.h>
file, if necessary.
- Added another test to <sys/time.h> to check if the "timeval" definition is
already in place. If it is, <exec/types.h> will not be included.
- <sys/time.h> can be made to define the timeval data structure locally if
the __USE_CLIB2_TIMEVAL preprocessor symbol is defined. In this case no
<exec/types.h> or <devices/timer.h> file will be read.
- The sprintf() family did not properly handle empty strings as format
specifications. This would result in a necessary buffer flush action
getting skipped, which consequently did not put the string termination
character into the output buffer.

- The parameters of atan2() were swapped. Fixed.
- Merged fdlibm 5.3 changes with __kernel_tan(), __exp() and __pow()
functions.

- The <assert.h> header file was missing the C++ 'extern "C" { .. }'
declarations.
- Added a new function __get_default_file() which allows direct access
to the low level file handle/socket descriptor associated with a
file descriptor.

- acos() now returns 0 for a domain error.
- asin() now returns 0 for a domain error.
- atan2() now returns 0 for a domain error.
- fmod() now returns x if y == 0 and sets a
domain error.
- sqrt() now returns 0 for a domain error.
- Added NaN and +Inf constants to the math library
initialization code which could come in handy later.

- Added "math_hypot.c"
- The 68k build makefile now builds the vfprintf/vfscanf functions
with %lld/%llu support.
- Split the release notes file into changes and actual release notes,
which may overlap but differ in technical content.

- Added "math_logb.c", and it appears to work, too.
git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@14706 87f5fb63-7c3d-0410-a384-fd976d0f7a62
- 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.

- 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().

- Modified __is_infinity() and __is_not_a_number() to use more portable
methods for accessing the low level representation of the IEEE 754
numbers they work on.
- Fixed a compiler warning in h_strerror()

- Added h_strerror() function to libnet.a; there's a global 'h_errno'
variable available, too.
- <signal.h> now defines a type 'sig_t'.
- <unistd.h> now allows the 'fd_set' type to be referenced as
'struct fd_set', too.
