This is a bug report for perl from muaddib@cheetah.mesas.com,
generated with the help of perlbug 1.34 running under perl v5.8.2.

[Please enter your report here]

Perl does not build properly out of the box on recent AIX version with
UCLA gcc 3.3.1.  There are two apparent problems:

 (1) Not all linker args are being wrapped with "-Wl," for gcc to pass
     through.  For example:  -H512 -T512 -bhalt:4 -bM:SRE -bE:perl.exp 

 (2) There is some strange and apparently inappropriate (at least,
     inappropriate to gcc) link step for libperl.a whereby a good
     shared object library generated by $(CC) is getting further
     archived by $(AR).  The end result similar to the following occurs
     at the beginning of "make test":

/tmp/perl-5.8.2$ LIBPATH=. ./perl -v
exec: 0509-036 Cannot load program ./perl because of the following errors:
      0509-150   Dependent module ./libperl.a could not be loaded.
      0509-103   The module has an invalid magic number.

Just for a little insight, when I apply only the following hack to
Makefile.SH, "make test" succeeds with no errors.  (I realize the
following patch would probably break xlC.C and vac.C).
