Well, over the past extended weekend, I finally got myself a fresh DJGPP
2.03 installation with the necessary sources, and started out trying to
get gcov to work. Turned out to be easy. The only thing that needed fixing
was that the files generated by 'gcc -fprofile-arcs -ftest-coverage' and
by running the so instrumented program had to be switched to binary mode.
gcov itself needed similar changed to read them as binary.

That's all there is to it. I did not make any effort to account for
systems that don't support "rb" or "wb" in fopen(), i.e. no BINARY_FOPEN
autoconfig stuff or so, so the patch is not 'FSF-clean', as it is.

For the reference: this all was done with current up-to-date gcc-2.95.2
and binutils 2.95.1 binary packages, and DJGPP 2.03. With older versions
of binutils, esp., I'd expect more problems. But I haven't tested that, at
all.

Even if all the snow were burnt, ashes would remain.
