AW: AW: AIX link error with g++ 4.4.0

[Fehringer Franz]

I used Dave Korns patch (with the addition of removing the LIBSTDCXX_STATIC #define in aix.h).

Hi David,

Thanks for info, should i still file a bug report (i did not find the time so far)?
With AIX 6.1 i do not have the problems you describe below (but on a second thought i do not link statically against libc.a).

Cheers

Franz

I have applied a fix to GCC mainline that uses LIBSTDCXX_STATIC as an additional library argument when linking statically, solving this problem.  I may backport this to GCC 4.4 if it proves safe.

While this solves the error about libstdc++ -lsupc++, I still receive other errors on AIX 5.3 when linking statically because ld tried to resolve all symbols in libc.a.  AIX 5.3 libc.a contains some references to functions that are not defined elsewhere.  I needed to use -Wl,-berok to generate a working executable.
