Hi,

I'm using svn trunk. I'll continue to debug this problem, but if you
know what it is ....

$ mount
C:\Program Files\NX Client for Windows\X11R6\lib\X11\fonts on /mnt/NX/fonts type user (textmode)
C:\cygwin\bin on /usr/bin type system (binmode)
C:\cygwin\lib on /usr/lib type system (binmode)
C:\cygwin on / type system (binmode)
C:\mingw on /mingw type system (binmode)
c: on /cygdrive/c type system (binmode,noumount)
e: on /cygdrive/e type system (binmode,noumount)
f: on /cygdrive/f type system (binmode,noumount)

O, I also got the silly Make error, where I need to change 
  ORIGINAL_LD_FOR_TARGET =
  C:/mingw/bin/../lib/gcc/mingw32/3.4.2/../../../../mingw32/bin/ld.exe
to
  ORIGINAL_LD_FOR_TARGET =
  /mingw/bin/../lib/gcc/mingw32/3.4.2/../../../../mingw32/bin/ld.exe
Do you do this each time?

#!/bin/sh

Now, I'm thinking the problem is, that it's using 
-B/mingw/i686-pc-mingw32/include instead of just /mingw/include.

Is this an easy thing to change in gcc with configuration, or do I need
to modify my mingw setup?

Thanks,
Bob Rossi
