Summary: AIX: configure ignores $CC; problems with C++ style comments

Initial Comment:
CC=xlc_r ./configure does not work on AIX-5.1, because configure unconditionally sets $CC to "cc_r":

	case $ac_sys_system in
	AIX*)   CC=cc_r
		without_gcc=;;


It would be better to leave $CC and just add "-qthreaded" to $CFLAGS. 

Furthermore, much of the C source code of Python uses C++ /C99 comments. This is an error with the standard AIX compiler. Please add the compiler flag "-qcpluscmt".

An alternative would be to use a default of "xlc_r" for CC on AIX. This calls the compiler in a mode that both accepts C++ comments and generates reentrant code.

Regards,
Johannes

Sorry about the C++ comments... all the C++ comments I have found concern
Windows, PC or Darwin. I must have confused this with another project
I have been compiling.

Though there still the issue with setting $CC.

There shouldn't be any C++ comments in the Python code.  If there are, it
is a mistake.  I did see some get removed recently.  Could you let me know
where you see the C++ comments?
