emerge xfractint ends just like that:

Apparently, xfractint wasn't tested with gcc >= 3.3.1. The new version of xfractint doesn't fix this problem. I'm attaching an updated ebuild for the current version and a patch I created. With this patch, xfractint compiles without any problems on my system.

patch for xfractint to compile with gcc-3.3.1

I've given a shot using your provided ebuild & patch to see how cleanly this
program compiles before resolving the bug, and hit a small snafu.

make: *** No rule to make target `helpdefs.h', needed by `ant.o'.  Stop.
make: *** Waiting for unfinished jobs....


Now the machine I used does not have X installed, so I'd expect the program
to not compile properly to begin with, but I was expecting an error explicitly
tied to X itself.  This error looks more with the program.  Any ideas how
this is resolved?

Sorry, I did test the patch but I forgot to check if the new version of
xfractint
works corretly with Portage. The problem is in the default '-j1' make option
Portage uses. Change 'emake' to "MAKEOPTS='-j1' emake" in the ebuild and
everything should work fine.

Why hasn't this been fixed in portage?  I just tried to emerge xfractint and I
encountered the same compiler error.

New version with the patch added to Portage.
