That really oughta read "ISO C++"... which still doesn't permit named
variadic macros.  :-)  They're a GNU extension and an addition to C99,
but IIRC the two are slightly different; someone else will have to say more.


['call of overloaded <C library function> ambiguous']

A very very active issue on the libstdc++ mailing list right now.  I thought
this was worked around, but your checkout may be earlier than the fix.

Both those compilers use an old, extremely noncompliant c++ library.
The issue with strcpy/std::strcpy (and the others) partially depends on which
header you included to get the declaration.  If it was <FOO.h> then plain
strcpy, memmove, etc, should work.  If it was <cFOO>, then the declarations
are only in std:: and you must qualify the calls (or use 'using', etc).

This is known to not work as well as it should be.

That doesn't look like gcc segfaulting (it would have produced a more
interesting error message).  That looks like soundserver.idl segfaulting,
while make was doing the commands to produce soundserver.h.

You can use gdb on the core file to see where and what happened.
