Problems with gcc -pg on RS/6000, AIX 3.2.2

Not sure if this is a bug or a feature...
Scenario: RS/6000-550 running AIX 3.2.2. We have the assembler
fix installed, and gcc 2.2.2 builds and runs correctly.
Problem:
Short form:
'gcc' works, but 'gcc -pg' dies in the assemble step with complaints
about '.mcount'.
Long form: See appended script file...
