This changes Python's standard profile-guided build target to work with
|
Studio instead of gcc. The unfortunate repetition of options seen below
|
is a workaround for build peculiarities and to meet Studio's requirement
|
that the profiling options be used at all steps of the build -- not just
|
compilation. As it is Solaris-specific, it is not suitable for upstream.
