GNU definition of C_WEAKEXT does not match AIX definition

[Graham Reed]

As of AIX 5.2, IBM has added some semblance of weak symbol support to
AIX.  (The static linker seems to behave itself, but the runtime
linker is a whole other story.)

binutils ./include/coff/internal.h defines C_WEAKEXT to be 127, and
notes it as a GNU extension.  Unfortunately, IBM used the value 111 in
the operating system.  Consequently, object files created by GCC and
the IBM linker cause the various binutils program to abort with an
unknown symbol type error.

The attached patch defines C_WEAKEXT to be 111 on AIX 5.2, and leaves
the GNU extension in on earlier versions.  It may be necessary to a
bit more coding and handle both cases, I only need to work with
standard AIX objects, so that's all I fixed.

Description: Patch to include/coff/internal.h

(See /usr/include/storclass.h to confirm the system's value for
C_WEAKEXT.)
