gcc4-core packaging bug

gcc4-core packaging bug

[Achim Gratz]

The package gcc4-core provides a compatibility symlink for programs that
expect the old gcc naming scheme (like Perl).  The link however is just
"gcc4", while Devel::CheckLib for instance looks for "gcc4.exe".

Achim.

Report that to the maintainer of Devel::CheckLib
It SHOULD NOT check for .exe suffix under cygwin.

Yes it should, since it does not need to know about the .exe magic
Cygwin performs.  Besides, it gets that information from %Config, which
in turn comes from Cygwin's own Perl.  Once the compatibility link is
named gcc-4.exe, the .exe magic ensures that both checking for an
executable named gcc-4 and gcc-4.exe will succeed, so that's the right
thing to do and not patching whatever number of Perl modules and/or
other build scripts.

Actually, the RIGHT thing to do is to have Perl (updated to 5.14.4 and) 
built without the CC=gcc-4 hack.

Oh, absolutely.  But until we have that, if anyone runs into troubles
that some program which hasn't been rebuilt since the gcc update is
unable to find a C compiler, add the .exe suffix to the compatibility
link.  I've only mentioned it here because I recently got a new machine
at work and wondered why I couldn't build some Perl modules anymore
until I remembered that I had re-linked the compilers on the old one.
