zillions of testsuite failures

[David Carlton <carlton@math.stanford.edu>]

Is anybody seeing lots of testsuite failures all of a sudden?  I'm
getting huge numbers; many, possibly all of them (e.g. every MI test
fails), seem to have to do with how GDB is invoked.  It seems like, at
some point, invocations start getting

  <directory>/testsuite/gdb.base/args 1 '' '' 3

tacked onto them.  E.g. the last line of gdb.sum is:

/extra/gdb/mirror/src/gdb/testsuite/../../gdb/gdb version  2003-01-15-cvs --args /extra/gdb/mirror/src/gdb/testsuite/gdb.base/args 1 '' '' 3

Looking at this a bit further, it seems like this 'global GDBFLAGS' that
args.exp sets is persisting for the rest of the entire test run.  So I
think there's something wrong with args.exp.

On a separate, I get the following results from gdb.base/advance.exp

Running ./gdb.base/advance.exp ...
PASS: gdb.base/advance.exp: advance line number
PASS: gdb.base/advance.exp: malformed advance
PASS: gdb.base/advance.exp: advance func
FAIL: gdb.base/advance.exp: advance function not called by current frame
FAIL: gdb.base/advance.exp: find line number containing "break here"
PASS: gdb.base/advance.exp: set breakpoint at call to func3
FAIL: gdb.base/advance.exp: continue to call to func3 in main
FAIL: gdb.base/advance.exp: advance function called as param
FAIL: gdb.base/advance.exp: advance with no argument

This happens before the args fiasco, so I think the failures are
legit.  Are they known?  I'll append the relevant part of my gdb.log
after my signature.
