[comp.unix.xenix] Why can't sdb read filenames that start with an underscore?

I had trouble getting sdb to read in the source file associated with 
a program I was debugging. Finally, after days of tinkering, I discovered
that it won't read in a source file that starts with an underscore. If
I renamed the source files, everything worked ok.

I RTFMed, and saw no mention of this weirdness. Is this true for all sdbs,
or just sdb as mangled by the SCO?  Does anyone know if there is any way
to get sdb to read in a source file that begins with an underscore? It
is inconvenient for me to keep renaming everything. (The source files
I'm debugging are generated automatically as output from a Pascal-to-C
compiler, and many other utilities depend on the names being as they are.)

Also, has anyone had problems with the 386 C compiler in the 2.3.x development
system generating bad code for packed arrays?
