Changes:
This release adds an alias for PAPI_ENUM_ALL to
prevent legacy code
from failing and adds support for nanosecond
resolution timers, newer
dual and quad core processors from Intel and AMD,
new systems from
Cray, Power6 with Linux, and standardized event
names. It fixes an
identification problem with some Pentium4 models,
overflow support on
Intel Core processors, Fortran headers for large
negative numbers, and
identification of POWER5+ and 5++ processors using
AIX. It improves
support for fork/exec with overflow and profiling,
and improves support
for FreeBSD.
