No. This is only affecting the ability of the test suite to kill the tests
when they hang indefinitely.

The cause is a bug in Fortran compiler detection. This has been fixed in the
upcoming 6.0.2. A temporary workaround would be to add the following lines to
your <hostname>.ac:

abi_cc_vendor="intel"
abi_cc_version="<your_version>"
abi_cxx_vendor="intel"
abi_cxx_version="<your_version>"

This is an ugly trick, but it might work.

"./configure --help" will show you the related options:

with_(cc|cxx|fc)_optflags

Yes. Hopefully this situation will be satisfactorily resolved soon.

Best regards,
