[Rainer Orth]

Neil,

your patch identified below causes a bootstrap failure on
sparc-sun-solaris2.8.

couldn't get off again ;-(

But I've found the patch causing this: -D 20010925 was successfull, -D
'20010925 00:55' fails to bootstrap:

gcc/dependence.c: In function `find_induction_variable':
gcc/dependence.c:487: parse error before 'd'
gcc/dependence.c:489: `__t' undeclared (first use in this function)
gcc/dependence.c:489: (Each undeclared identifier is reported only once
gcc/dependence.c:489: for each function it appears in.)
gcc/dependence.c:489: parse error before ')' token

I've included the diff between dependence.i from the successful and failed
builds below.
