Also return "1" rather than "-1". According to bde: -1 is unrepresentable.
Exit statuses must be >= 0 and <= 255, at least if chars are 8 bits and
shorts are 16 bits. This seems to only be documented indirectly in exit.2
by referring to wait.2. WEXITSTATUS() throws away all except the low 8 bits
of the status returned by _exit(), and the kernel actually only stores 8
bits of it (if chars are 8 bits, etc.), so wait() can't return any more bits.
Obtained from: rev 1.4 of contrib/gcc/gcc.c
if compiling with -fformat-extensions). Gcc's format checker never
actually supported %q length specifiers. It treats %q as an alias
for %ll, which is correct if quad_t is long long (e.g., on i386's)
and broken otherwise (e.g., on alphas).
quad_t's currently should be printed in the same way that they
already need to be printed to avoid compiler warnings on all
supported systems: cast them to a standard type that is at least
as large (long or long long) and use the length specifier for that
(%l or %ll). This is problematic since long long isn't standard
yet. C9x's intmax_t should be implemented soon.
Don't accept %L length specifiers in the kernel either. The only
legitimate ones are for long doubles, but the kernel doesn't even
support plain doubles. (gcc bogusly accepts %Ld as an alias for
%lld, and it sometimes prints "q" in error messages about "ll" and
"L" length specifiers, becauses it represents all these specifiers
as 'q'.)

- plain %r and %z were disallowed. The hard NULs in the warnings were
hopefully caused by disallowing of plain formats being nonsense.
- new formats for shortening to a byte were allowed, but even the libc
printf doesn't support them.
- old %hr and %hz formats were allowed, but the kernel printf doesn't
support them. The kernel doesn't support %hd either, but this is
harder to fix.

* Consistantly put spaces after "," in macro param lists
* Consistantly align continuation characters.
* Don't need to supply all variations of __FOO__ in CPP_PREDEFINES,
gcc will do that for us.
Our malloc can allocte pagesized blocks efficiently and the EGCS default size
of 4072 bytes is not optimal.

Until I have a chance to look at what that problem is and to carefully consider
the upgrade issues of turning it back on at a later date if we leave it turned
off for any extended peroid of time.
While I have yet to hear of any problems with us using thunks. The EGCS
mailing list notes some have problems with it and not using them are a
safer default. People wanting to use them, can set the appropiate
compiler flag.
