I installed GCC 2.1 on our Sun-4s, and realized that there is no tcov support
from GCC.  However, GCC supports the -a option, but does not create a suitable
.d file for the block count/profiles to be written to.

I have been poring through the source code, and have found the place(s)
where such a file must be created, when the profiling code is actually
generated, how it has to link with /usr/lib/bb_link.o, and so on.
However, I haven't been able to figure out the "block structure" assumed
by GCC with respect to actually, writing line numbers into the .d file.

Any idea if there is a patch for this, or do we have to manage without tcov for
code coverage?

Appreciate your input....  Thanks...
