Well, I'm no longer convinced the bug is in the g77 front end.  I'll
try to investigate further, maybe by trying to build a cross-compiler
for one of the targets.

Is this problem happening only on systems with 64-bit-ness, e.g.
where `long int' is 64 bits but `int' is 32?  It might be that
the gcc back end isn't properly handling ADDR_EXPR(NOP_EXPR(VAR_DECL))
where the VAR_DECL is SImode but the NOP_EXPR is DImode, or something
along those lines.
