also a bunch of gcc options are being passed to CC, odd
I set CXX=/usr/bin/CC to get here.

also lots of warnings about mixing extern "C" and not:

"../../gcc-4.5/libcpp/files.c", line 1173: Warning (Anachronism): Formal
argument 2 of type extern "C" unsigned(*)(const void*) in call to
htab_create_alloc(unsigned, extern "C" unsigned(*)(const void*), extern "C"
int(*)(const void*,const void*), extern "C" void(*)(void*), extern "C"
void*(*)(unsigned,unsigned), extern "C" void(*)(void*)) is being passed
unsigned(*)(const void*).
"../../gcc-4.5/libcpp/files.c", line 1173: Warning (Anachronism): Formal
argument 3 of type extern "C" int(*)(const void*,const



and other errors related, mixing said in ternary, like:


foo = foo2 ? foo2 : foo3;
 (as in reallocator = set->reallocator ? set->reallocator : xrealloc)


where foo2 and foo3 vary in extern C-ness.
workaround is
foo = foo2
if (!foo)
  foo = foo3

even though that doesn't seem different enough -- I understand there is the
problem of figuring out a type for the ternary operator, but there is also the
matter of being able to assign the function pointers



here's an example of the obtack_free problem, either I didn't get all the
obstack.h files fixed or the cast needs to be void* or something:


"../../gcc-4.5/libcpp/files.c", line 1193: Error: Cannot assign char* to int.
