gcc/g++ snapshot bug

[D.W.Howells <dhowells at astarte dot free-online dot co dot uk>]

I'm not sure whether this is a problem with your (CodeSourcery's) build of 
gcc/g++ snapshot RPMs, or whether it's a general problem with the gcc/g++ 
installation, but when I installed:

	gcc-snapshot-20010130-1.i386.rpm
	gcc-snapshot-c++-20010130-1.i386.rpm

The compiler specific C++ header files (for instance: bits/c++config.h) don't 
end up in the compiler builtin include path:

	dwh>ls /usr/local/i386-pc-linux-gnu/include/g++-v3/bits/
	atomicity.h  c++io.h      c++threads.h  ctype_inline.h     os_defines.h
	c++config.h  c++locale.h  ctype_base.h  ctype_noninline.h  std_limits.h

Whereas the compiler specific C header files do:

	dwh>ls /usr/local/lib/gcc-lib/i386-pc-linux-gnu/2.97/include
	README   iso646.h  proto.h   stdbool.h  syslimits.h
	float.h  limits.h  stdarg.h  stddef.h   varargs.h

I ran the preprocessor with the verbose flag to see where it actually looked 
(you'll have to excuse the word-wrapping problems, but kmail refuses to turn 
it off):
