Subject: perfctr-2.6.12 released

Version 2.6.12 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/

Version 2.6.12, 2004-12-19
- PPC32 driver updated to be more robust in its detection of
  timebase and core clock frequencies. Some information sources
  can give wrong values for those frequencies, so the driver
  now tries other more reliable methods first.
- On x86/x86-64, perfctr_event_codes.h now includes P4 events.
- On x86-64 libraries will now be installed in PREFIX/lib64/,
  as per current standards, unless overridden by LIBDIR.
- Perfex had a bug in which it interpreted all numbers as hex,
  even those without "0x" prefixes. Perfex now emits warnings
  for ambiguous numbers. To silence the warnings, (a) prefix
  hex numbers with "0x" (preferred), or (b) use the "-d" option
  to enable decimal numbers, which requires "0x" prefixes on
  hex numbers, or (c) use the "-x" option to force all numbers
  to be interpreted as hex (deprecated). The "-d" option should
  be the default, but unfortunately that would break user-level
  scripts that assumed that "0x"-less numbers are still hex.
- Changes in examples/signal/ to handle glibc-2.3.3 on PPC32.
