[jdswinbank (John Swinbank)]

As per subject, this portfile updates to the 4.13.4, released 2012-04-02.

By the way, in #28759 I was asked to remove variants for older versions of gcc, but I see the file which was actually committed to Macports had them included. I've removed them again here since I only tested with gcc46.

I don't see anywhere in #28759 where anyone asked for gcc variants to be removed. I only see my comment which said "gcc45 should only be the default variant if the user has not already chosen the gcc44 variant". I was referring to the line "default_variants +gcc45" which would have caused an error message for users who requested the +gcc44 variant. See wiki:PortfileRecipes#default_variants and wiki:PortfileRecipes#gcc for the proper recipe. I also said "Fewer variants is better" but I was not intending for that remark to be interpreted as applying to the gcc variants, but rather the other variants. I would not suggest removing gcc variants; rather I would advocate adding a gcc47 variant to those already there, so that users can use the latest stable version. Mixing different gcc versions in different ports can sometimes lead to problems, and gcc45 is the default version of gcc that we use in other ports at this time, so certainly at least the gcc45 variant should be retained.

Apologies if I misinterpreted the desire to trim down on variants.

The latest revision reinstates the gcc44 and gcc45 variants as well as working around an issue in which Macports thought libpgsbox was incorrectly linked.

Attaching an update portfile diff which bumps the version to 4.14 and adds support for GCC 4.7.
