That would be in the cygwin distribution.  In later snapshots it's called
"winerror.h.  If you grep for "ERROR_" you should be able to find the
correct file, whatever it is called.

Error 87 is "INVALID_PARAMETER".  I'm not sure why this is happening,
unfortunately.

Sorry.  I don't know anything about the search engine.  Possibly sending
email to sourcemaster@cygnus.com might help.

If you want to debug this, you could grab a precompiled version of gdb from

ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/cygwin/ports/

possibly, that would work better.
