egcs-1.1: AIX problems

[Andrey Slepuhin <pooh at msu dot ru>]

Hi Jeffrey,

Before egcs-1.1 release I want to ask about a status of some
egcs problems on AIX.

1) What about multithreading support on AIX? As I understand,
   --enable-threads configure option now stands not only for objc,
   but it should enable generation of thread-safe libraries. If yes,
   what changes are necessary to do this on AIX? Note, if
   thread-safe exception handling will be enabled, then only -mthreads
   compiler option is needed.

2) What about a status of David Edelsohn's patch solving the
   __builtin_setjmp problems with shared libraries? This patch never
   was merged into main tree, though it works fine for me.

3) What about a problem with duplicated typeinfo nodes? Jason said,
   that we need another method of comparing typeinfo nodes on platforms
   where linker cannot resolve duplicated symbols into unique instance,
   but I don't see any changes. And this problem makes usage of shared
   libraries with RTTI and exception handling hardly possible.

If these problems cannot be solved in egcs-1.1, can we hope that they will be
solved in the future? And is there any activity on these problems?

Best wishes,
