This autoconf test is generating non-compliant code, and emulating GCC's bug
would be non-trivial.  This:

  &(diags+5)[-1] == &diags[4]

is not an integer constant expression, therefore it can't be used to initialize
a global in C.  Perhaps the xlcbug case can be ifdef'd with an xlc-specific
macro or something.
