Pierre already submitted an argument against this (the likelihood of the
bug may be reduced in CVS). Here's another argument: it is sometimes
impractical to either replace the existing DLL or replicate the same exact
environment for a debug version. Why not debug exactly what fails?
Besides, since the releases aren't tagged in CVS (yes, that old quibble
again), it's a gamble on whether you're even building the right version...

Agreed. So we don't teach them to debug, we simply provide them with

Also agreed. But the source provided in the cygwin source package is
worthless for debugging, since one can't build Cygwin from that source.
If debugger symbols were available, that source would actually be useful.
