Maybe.  That might explain the $5000-$10000 reference.  I'd be surprised
to hear that people are cognizant of that level of detail about these
tool offerings, though.  WindRiver certainly doesn't advertise Cygwin
and Red Hat itself just calls these tools GNUpro for Windows, the last I
checked.

Um, yeah.  I wasn't wondering why people were having problems building
cross compilers.  I know that that is difficult.  I certainly never
mastered it before I started at Cygnus.

Or, maybe the misinformation you're referring to is even more basic than
"How do I build a cross-compiler?"  It does seem like a lot of people
expect to get cross-compilation out-of-the-box.

Yep.  That's what this mailing list is for.  Helping people use Cygwin
and Cygwin tools.
