This should not cause a warning to happen.

Can you provide the preprocessed source?

This works for me with:

Preprocessed source where the problem occurs for the first time

team.c also shows the problem, this is just the source corresponding
to the original error.
Comment 7 Andrew Pinski 2010-03-29 22:17:45 UTC 
I just was about to bootstrap with [trunk revision 157804].
Comment 8 Richard Biener 2010-03-30 14:21:38 UTC 
It doesn't warn for me.  Please provide -v output of the command that warns
for team.i or parallel.i.

Output obtained from adding '-v" to the 32/libgomp Makefile

Here's the output of "make", just after having added "-v" to
the options of the relevant Makefile.
Comment 10 Richard Biener 2010-03-30 15:16:45 UTC 
Err,

cc1: error: unrecognized command line option "-fsave-temps"

but - still works for me.  How did you configure?

Sorry, that should have been -save-temps.

I added this to the Makefile in x86_64-unknown-linux-gnu/32/libgomp by
hand and messed up that particular option.

This is better:

Closing as invalid.
