92d8b1e9fa Revert previous: .S files are currently compiled with -traditional-cpp, 
so __STDC__ is _not_ always defined.

010758bf16 Add SIGFPE support to SoftFloat, so fpsetmask/fpgetmask now work. A new 
variable, float_exception_mask (#defined to _softfloat_float_exception_mask)
contains the current exception mask.
Also make the argument to float_raise into an fp_except.
Also synchronise file header comments between files.

251de84ccc Consistently declare the types of float_rounding_mode and float_exception_flags 
as fp_rnd and fp_except respectively.

25540eca7e All the versions of softfloat-specialize were practically identical, so replace 
them with a single one.

2d8577fb83 Clean up some rampant code duplication wrt ieee number handling: 
- Add alignment-safe double and float unions.
 - Use the above for the __infinity and __nan constants on all
   architectures that use the standard ieee754 representation of
   those constants.
 - Add a single copy of various ieee754 math functions (frexp, isinf,
   isnan, ldexp and modf) that had numerous duplicates among the
   arch-specific directories.
 - Use the above functions on all architectures where the generic C
   versions where used.  Architectures that had local assembly
   routines are untouched (for those functions only).

ac8c1c29e9 * Add WSYSCALL() to SYS.h, which creates a system call with an 
internal name and a weak alias for the name.
* Add a WEAKASM syscall list, and process it.
* Make sysarch() have an internal name (_sysarch()).

9870327734 fix syscall() and __syscall(). r0 has to be set to SYS_syscall or 
SYS___syscall, respectively.  otherwise sys/arch/sh3/sh3/trap.c will
look at the wrong argument.

985033a7a6 Add fixunssfsi and fixunsdfsi. These are provided by libgcc2.c in GCC 2.95, 
but not in EGCS.

This version of fixunssfsi is almost exactly the arm32 version.  fixunsdfsi is
mostly based on fixdfsi, but with simplifications for 64-bit integers.

Only minimal testing has been applied so far.

On m68k ELF calling standard (__SVR4_ABI__), if a function
returns a pointer, the return value should go to a0 as well as d0.
