ExtUtils-CBuilder 0.12

on Perl CPAN

In order to integrate into the perl core, patches were contributed
that a) put a $VERSION variable in each .pm file, b) add a 'quiet'
parameter to new() to shut up some of the command-echoing, c)
checks for the perl source headers in the CORE/ directory in the
perl source tree, not in the post-installation location, and d)
adjusts the CWD when running the regression tests under the perl
core. [Yitzchak Scott-Thoennes]

Various parts of the code were looking for the CORE/ directory in
$Config{archlib}, $Config{installarchlib}, and $Config{archlibexp}.
Only the latter is correct, so we use that everywhere now.
[Curt Tilmes]

For Unix-ish platforms, link_executable() will now prefer
$Config{cc} to $Config{ld}, because that typically works
better. [Jarkko Hietaniemi and H.Merijn Brand]

Prelinking (invoking ExtUtils::Mksymlists to create options-files)
is now only done when we're building dynamic libraries. [Yitzchak
