Hi!  Sorry for bringing bad news:

Sounds great except it appears you forgot to run this past
all targets.  The new gas test doesn't work if the target
has '@' in line_separator_chars[] or tc_symbol_chars[], like
for cris-elf and mmix respectively:

Running /x/src/gas/testsuite/gas/macros/macros.exp ...
FAIL: macros count

A glance at gas.log for these targets shows that gas gets
confused and loses track, in different ways.  Probably
fixable rather than requiring target-skipping for the test,
since the @ is "\-escaped", but I think I'd better leave
that to you.
