Release: gcc version 2.97 20001221 (experimental)
Environment: hpux 10/11
The Originator can no longer replicate this with a gcc 3.0 (prerelease)
version. It use to also happen with zlib/{trees,gzio}.c but no longer
does with 3.0 20010430 (prerelease) on hppa2.0-hp-hpux10.20.
It was probably fixed before the following went in.

* flow.c (propagate_on_insn): Make trying to delete a prologue
or epilogue insn an ICE, not a warning. Allow doing this if
the current function returns with stack pointer depressed.
