When I try to build gcc cross-compiler using crosstool-ng under Cygwin (running in Windows 7) I have the following message:

$ /opt/ng-crosstool/bin/ct-ng build
[INFO ]  Performing some trivial sanity checks
[ERROR]  Your file system in '/devdir/.build' is *not* case-sensitive!
[00:02] / make: *** [build] Error 1

I try to add in \etc\fstab (as recommend here):

C:/forbuild /forbuild ext3 binary,posix=1

but it doesn't help However, when i run mount command i have the following result:

C:/cygwin/bin on /usr/bin type ntfs (binary,auto)
C:/cygwin/lib on /usr/lib type ntfs (binary,auto)
C:/forbuild on /forbuild type ntfs (binary)
C:/cygwin on / type ntfs (binary,auto)
C: on /cygdrive/c type ntfs (binary,posix=0,user,noumount,auto)
D: on /cygdrive/d type ntfs (binary,posix=0,user,noumount,auto)

What's the problem? How i can use crosstool-ng in Cygwin?
