Hi Pavel,
as requested, here's two sets of rebased improvement patches to simplify
fixing AIX problems (at least), to be subsequently imported into gcc.

* m4/libtool.m4 (LT_PATH_NM): Detect POSIX-compatible nm for AIX. In
BSD mode, the AIX nm does not tell whether a symbol is weak, need to use
POSIX mode instead.
(_LT_CMD_GLOBAL_SYMBOLS): Support POSIX-compatible nm. Reorder to allow
for platform specific hooks during transformation of global_sym
* m4/libtool.m4 (_LT_LINKER_SHLIBS): On AIX, GNU g++ generates
_GLOBAL__* symbols as, amongst others, landing pads for C++ exceptions.
These symbols must not be exported from shared libraries, or exception
handling may break for applications with runtime linking enabled.

To compile 64-bit, AIX toolchain provides support to set the environment
variable OBJECT_MODE=64, to avoid the need for changing anything else in
the build environment. However, gcc ignores OBJECT_MODE, and does not
set it while building gcc itself during its multi-lib build either.
Also, CC may be
Hi Michael,
I had a look since I wrote a patch for POSIX nm a couple of years ago
that I never submitted (I didn't see any use case) which looked very
similar, excepting the AIX-ism in your version.
