ion)
../../gcc/gcc/ada/decl.c:6165: error: (Each undeclared identifier is reported on
ly once
../../gcc/gcc/ada/decl.c:6165: error: for each function it appears in.)

Unfortunately, the MAX_OFILE_ALIGNMENT on the PA under HP-UX depends on
whether or not a variable is placed in common.  The maximum alignment
in common is only 8 bytes.  I can't reduce MAX_OFILE_ALIGNMENT to 64 without
breaking other stuff.  In the other places where MAX_OFILE_ALIGNMENT is
used, I can access the declaration and do an appropriate test.  However,
this isn't going to work in ada/decl.c.
