Change 29847 by [EMAIL PROTECTED] on 2007/01/17 12:30:43
Integrate:
[ 27027]
Intel C Compiler 9.0 hatefully defines __GNUC__. Unfortunately,
icc does not support gcc built-ins like __attribiute__.
[ 27568]
Fix some test failures in t/op/cmp.t when compiling with the Intel
C++ Compiler on Linux.
[ 28566]
Keep Intel C++ from claiming that it is gcc.
[ 28728]
Additional floating point strictness is needed to get Intel cc to pass
its tests.
