Hello,
here is a new version of the patch. Differences with the previous one
should only be comments, testsuite, printing types and inhibiting error
messages.
Passes bootstrap+testsuite. scal-to-vec1.c was failing but then Joseph
showed me the \[^\\n\]* trick and I retested with:
make check-gcc 'RUNTESTFLAGS=dg.exp=scal-to-vec1.c'
