Hi,
configure checks if contrib/compare-debug actually works for comparing a
debug and non-debug .o file before enabling bootstrap-debug. But some
compilers encode some command line options (among them -g) into a special
.comment section. This patch removes .comment section before comparing
debug and non-debug files. OK for trunk?
Thanks.
