- So far this works fairly well for me for building applications
using clang as a gcc substitute. If you are using ccc for a
different purpose and this is a problem, speak up! Note you can
also use CCC_NATIVE=0 to disable.
- Also, turn CCC_ECHO off as default.
- Also, pass through -Wl, to linker.

One might anticipate that at some point I will just break down and go
through the man page. That seems a little too obvious.

- Support environment variable CCC_LANGUAGES to control which
languages clang is invoked on. If unset clang is invoked for all
languages, otherwise CCC_LANGUAGES should be a comma separated list
of the languages (as accepted by -x) for which clang should be
invoked. Useful for only building C and Objective-C parts of a
project with clang, for example.
- Add environment variable CCC_FALLBACK. If set and non-empty then
ccc will try and compile using the regular compiler if compilation
with clang fails.
- A few other tweaks to add options, flush stdout, recognize .mm as
objective-c++, and infer languages for compile+link style
invocations.

- Use CCC_ECHO to control echoing behavior (default is on, set to ''
or unset to disable)
- Get 'clang','llc','as','cc','ld' executables from environment. 'cc'
and 'ld' are fetched through CCC_CC and CCC_LD respectively -- to
support make CC=ccc -- the others are through their upcased
versions.
- Add CCC_NATIVE mode.
o This uses llc and as to generate native object files; allowing
more drop-in replacement of gcc.
o Disabled by default, but should eventually be default.
o Allow --emit-llvm in CCC_NATIVE mode to override. Essentially
this makes ccc more like a drop in replacement for llvm-gcc.
- Prevent explicit -x <language> options from annoying clang.

since handling this correctly is quite complex, and on some platforms
requires additional -D options and on some implies linking against a
different libc, but this works better than just ignoring the option.
The other change passes the -x option across to clang, which allows
compiling .c files as Objective-C and so on. For some reason a lot of
configure scripts seem to be under the misguided impression that this
is a sensible thing to do."

not in the current directory. This doesn't work with VPATH builds in
autotooled builds.
- ccc now creates object files without an extension.
- Return exit code 1 if code > 255.
