gcc vs g++ and linking with as

[Chris Howard <choward at intellistor dot com>]

binutils 2.9
gcc/g++ 2.8.0

Host Sun Sparc Solaris 2.5
Target Motorola Coldfire (-m5200)  a.out object format

Not using stdlib  (-nostdlib)

We have some code in assembler, and some in C.
Compiling with as,gcc and linking with ld works fine.
Compiling with as,g++ and linking with ld does not work,
  undefined symbols for those things written in assembler.

The .o files output from g++ compilation have exported symbols that
end in '__Fv' whereas the assembler output .o files don't have
'__Fv' on the symbols.  Is that the problem?  Is there
some way to make it work?  What is __Fv?


An alternative might be to put the assembly code in
C/C++ wrapper functions.  Any hints/comments that
would be appreciated also.
