I have a few years under my belt (come to think of it they are
threatening to engulf my belt). For work, I'd do what's necessary to
integrate the little thing into the big thing. For this I don't want
to work too hard on side issues unless I decide they are interesting
side issues.

The GCC driver uses -gdwarf2 if you do 'gcc -g' on a .s file. Using
-gdwarf2 with assembly code manually or through gcc is successful in
producing a Cygwin64 executable that Cygwin64 GDB can work with. This
combination of circumstances led me to wonder how stabs was chosen for
Cygwin64.

When I cobble together an I/O system for the language's runtime, I
will probably switch the project to Linux-only. I/O is one of the
interesting side issues I wish to tackle.
