Patches for egcs-971016 on AIX

[Andrey Slepuhin]

Hi,

I just prepared patches for egcs-971016 on AIX 4.2 with native ld
(patches are
attached). These patches solve the following problems:

1) Automatic generation of shared objects using native ld (by explicitly
defining
exported symbols in separate file). Now you can simply type:
g++ -shared -o <shared_object_name> obj1 obj2 ... 

2) Now you don't need to pass -bnoquiet option to linker when object
files are
compiled using -frepo option. I added one more check for undefined
symbols
into tlink.c.

I tested these patches only on AIX 4.2, but they must work for any 4.*
version,
because I didn't use any AIX 4.2 features. Note, that patch for shared
objects
is only a workaround, because it would be better to generate export list
directly
by collect2 (it is already parses object files to export global
ctrs/dtrs; sorry,
I don't know xcoff format and I can't make appropriate changes myself).
