Subject: perfctr-2.6.14 released

Version 2.6.14 of perfctr, the Linux performance monitoring
counters kernel extension, is now available at the usual
place: http://www.csd.uu.se/~mikpe/linux/perfctr/2.6/

Please note the subtle semantic change in vperfctr_open().
Some users, notably PAPI, need it, but it's possible that
it breaks things for other users. If you're affected, please
report that and I'll update the API so that the old semantics
can be expressed again.

Version 2.6.14, 2005-04-09
- Changed vperfctr_open() so that if the thread already has
  an attached perfctr state, then the call fails with EEXIST.
  This allows self-monitoring code to detect if it is under
  the control of an external monitoring agent, before it
  changes the counters' control setup.
- Reverted the workaround in perfctr-2.6.13 for the problem
  that gcc-4.0 snapshots broke the x86/x86-64 low-level driver,
  as recent gcc-4.0 prereleases seem to work correctly.
- Updated kernel support: 2.4.30, 2.6.12-rc2, and 2.6.9-5.0.3
  (RHEL4).
