	You said "Cygwin", not "Mingw".  As Earnie noted on the mailing 
list, "Mingw" is not "Cygwin".  Also, afaik, Mingw does not 
support symlinks.

	Since you said above that you had downloaded and are using 
Cygwin, then you might want to try using this -mno-cygwin switch 
as well...that is if you want to build Mingw apps under 
"Cygwin".

	"Cygwin" requires -mno-cygwin to do mingw compiles.  GCC from 
Cygwin is not the same GCC from Mingw.  They are different.  
Cygwin gcc needs cygwin.dll to work, mingw does not.

	As noted on the mailing list, this is not a Mingw concern...it 
is a Cygwin concern.  You might want to mention it on the cygwin 
mailing list if you still have any doubt about what people are 
telling you...

	*ahem*...you can not have a Mingw compiler if you are using 
Cygwin.  You _can_ use Mingw runtime headers, which is what the -
mno-cygwin switch is there for.  It is also the reason why the 
Cygwin distribution includes a directory for Mingw (see 
usr/include/ under Cygwin).

	Yes, for a Cygwin compiler, you do.
