    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

Created attachment 25960
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25960
preprocessed exclude.c

Under last Cygwin (XP 32bits) and with gcc-4.7-20111119, i get this message
with exclude.c (directly from the rsync-3.0.9 distribution), see
attachment (preprocessed). No problem with other platforms (Darwin PPC or
Intel,
Ubuntu at least).

This might have something to do with #51271.
However, i cannot reproduce the minimal test case given under
the first comment of that bug report.

% gcc -O2 -o exclude.o -c exclude.c
exclude.c: In function 'get_cvs_excludes':
exclude.c:943:1: internal compiler error: in maybe_record_trace_start, at
dwarf2cfi.c:2244
Please submit a full bug report,
with preprocessed source if appropriate.
