The slowdown started on 2001-04-18. These are the diffs for that
day:

-----------------------------------------------------------------------------
Tue Apr 17 21:41:11 2001  Jeffrey A Law  (law@cygnus.com)

	* jump.c (mark_all_labels): Canonicalize the tail recursion
	label attached to CALL_PLACEHOLDER insns.

2001-04-17  Kaveh R. Ghazi  <ghazi@caip.rutgers.edu>

	* output.h (dump_flow_info, free_basic_block_vars,
	which_alternative): Delete redundant prototypes.

	* rtl.h (bss_section): Likewise.

2001-04-17  Loren J. Rittle  <ljrittle@acm.org>

	* dbxout.c (N_OPT): Define if not available from <stab.h>

2001-04-17  John David Anglin  <dave@hiauly1.hia.nrc.ca>

	* vax.h (PROMOTE_PROTOTYPES): Define for compatibility with system
	libraries and native K&R compilers.

The only one that seems relevant for SPEC is the first one. Note
that I have only quickly scanned the logs. I have not tested
anything yet.
