My rough estimate is that yes, about half of errors will be generated
not on the line flagged as ERROR, but I haven't looked at the whole B
tests, just enough to realize that it is a huge task.

I believe the 3 CE tests doing smart things with filenames have been
removed, I have to recheck otherwise I won't bother with them.

I plan to commit with all macro substituted, most macro deal with the
testsuite being tailored to one special compiler, and we have only one
compiler out there :). GNAT handles platform specific stuff using
Standard'Attribute in a uniform source way, no need for target macros
as far as ACATS for GCC is concerned.
