p5.28-unicode-utf8 fails on 10.5 for compiler standard

The port already contains

compiler.c_standard 1999

why isn't it passed to gcc-4.2 ? IIRC it needs to enable -std=c99 on old gcc .4x series, shouldn't it?

I tried forcing MP ggc 4.8 (here on intel it works, on PPC not for other bugs)

sudo port -v upgrade p5.28-unicode-utf8  p5.30-unicode-utf8     p5.34-unicode-utf8  configure.compiler=macports-gcc-4.8

but it still tries to build with gcc 4.2 as the error shows:

compiler.c_standard instructs MacPorts to select a C compiler that supports that standard. It does not guarantee that that compiler defaults to that standard, nor does it attempt to set any -std= flag; it's up to the build system or the Portfile to do that.

Without seeing the build log I can't answer this one, but perl is broken by design in that it insists on using the compiler that perl was built with to build all perl modules. I thought we were trying to work around that in the perl5 portgroup but maybe it is not working generally or not working just for this port.
