The default gcc is defined by the gcc-defaults package. This
is architecture specific. As far as I understand, the default is gcc-3.3
on all arch but sparc-linux where it is 3.2.

The problem is you cannot know which version of gcc/gcc-default was
used by the buildd.

Recent sbuild (>=1.170) print something like

Toolchain package versions: binutils_2. gcc-3.3_1:3.3-3
g++-3.3_1:3.3-3 libstdc++5_1:3.3-3 libstdc++5-3.3-dev_1:3.3-3

in the build log, but the m68k buildd q650 is still using sbuild

To work around that, you can add something like
gcc --version 
in your debian/rules.

As for the specific problem, I guess you are speaking of #199013. I
agree with you that there is something strange: simply rebuilding 
jade on crest fix the problem, but the autobuilt package is buggy.
Maybe there is something wrong inside the buildd.

I would advise you to add a check that nsgmls is basically working
with libsp in debian/rules, so that buggy packages are not uploaded.
At least this will give us the option to build it manually on crest
until the issue is sorted out.
