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.

Output obtained from adding '-v" to the 32/libgomp Makefile
Here's the output of "make", just after having added "-v" to

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:
