* be consistant on protecting "#define FOO"s with "#undef FOO".
* be consistant that macro params are upper case, and commas are followed
by a space in the macro definition
* protect macro param expansion by ()'s
* break long lines
* line continuations chars to consistant column
* remove trailing spaces
FreeBSD wide config file.
This includes "WORD_SWITCH_TAKES_ARG" & "SWITCH_TAKES_ARG". Platforms
such as FreeBSD/MIPS will need to override these two defintions, but it
can #undef them and define them approapiately.
* Support for our dual ELF/a.out building ability
* Our custom ASM_* definitions
* Our custom debugger and profiling related definitions
* Our custom STARTFILE/ENDFILE specs
* The stock EGCS 1.1.2 freebsd-elf.h file depended on
egcs-1.1.2/gcc/config/linux.h, which included "svr4.h". We will
include "svr4.h" via our "tm.h" definition. So add the few bits
from "linux.h" we actually needed.
* Using our current crtbegin.o/crtend.o we cannot support the DWARF2
unwinding mechanisms. In the future we will switch to the
non-sjlj-exceptions type exception machanism. However the `make world'
bootstrap problems with the EGCS crtstuff.c must be overcome first.
* Our a.out gas doesn't "know" to use NOP's for aligns while in the text
section. Thus the a.out alignment generation needed tweaking from
what we did with GCC 2.7.2. [from BDE]
* The definition of SUPPORTS_ONE_ONLY prevents the compiler from trying
to use "linkonce" sections for a.out. The definition of
NO_DBX_FUNCTION_END we had causes it to avoid .stabs symbols that the
assembler cannot handle for a.out. [from JDP]
* The previous "EXCEPTION_SECTION_FUNCTION" is the wrong name for EGCS.
It also needed tweaking for EGCS. [from JDP]
Also bump __FreeBSD_cc_version to 400002 in case we need to know we are
using EGCS at some point.
* 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.
* Turn on DEFAULT_VTABLE_THUNKS. (it is the default anyway, I'm just being
explicit about it, in case it causes us trouble it might be easier for
someone to notice it this way)
with a numeric value that describes the feature level of the
compiler. This can be used to check for the presence/absence of
FreeBSD-specific compiler features. The value is a decimal number
whose digits have the form VRRRRFF, where:
V = Compiler vendor. 0 (elided) means gcc.
RRRR = Vendor's version number, e.g., 2721 for the current
gcc version (2.7.2.1).
FF = FreeBSD-specific revision level. 00 means the stock
compiler from the vendor.
The value of "__FreeBSD_cc_version" is hard-coded in
"src/contrib/gcc/config/i386/freebsd.h" and must be incremented
when new FreeBSD-specific compiler features are added. I considered
simply picking up the value of FreeBSD_version from <osreldate.h>.
But that would break cross compiles of gcc.

the executable file, so it will work for both a.out and ELF format
files. I have split the object format specific code into separate
source files. It's cleaner than it was before, but it's still
pretty crufty.
Don't cheat on your make world for this update. A lot of things
have to be rebuilt for it to work, including the compiler and all
of the profiled libraries.
