gcc-4.6.2 can't complete make

I have started again, moving objdir outside the gcc-4.6.2 source code directory.

My configure completes, however I still get errors which look remarkably like this:


/home/User/objdir

make install;

fib2_ui.c:76:29: error: 'FIB_TABLE_LIMIT' undeclared (first use in this function)
fib2_ui.c:76:29: note: each undeclared identifier is reported only once for each function it appears in
make[5] *** [fib2_ui.lo] Error 1

make[1] *** [stage1-bubble] Error 2
make[1] Leaving directory '/home/User/gcc-4.6.2/objdir'
make: *** [all] Error 2

So why on earth does my make halt where it does?
