After reading the man page for gcc/g++, I'm still not sure how to see
the intermediate C code from g++.  What flag do I specify on the 
command line? 

Thanks for any info,
Roldan

There is no intermediate C code from g++.  It goes straight to assembler,
as most non-cfront-derived C++ compilers do.

Furthermore, it appears, from work presented at the Usenix C++ Conference
in Portland, that there is a substantial performance penalty for any
attempt at a portable implementation of exceptions if you are required to
produce C code.  Unless major mistakes were made, this suggests that in
the future, compilers like cfront will fade away since they won't be able
to compete with straight-to-assembler implementations.

There is no intermediate C code, because g++ is a native compiler.
That is, it generates assembly directly from the C++ program, without
acting as a "translator" to convert the C++ into C.
