You need to put mingw in winsup/ and then compile.

I straced it (and the problem went away) so, I straced 'bash -c mount'

The 'writev' takes 11.2 seconds to complete. Could somebody give me a
hint what is going on here?
The timestamp isn't time to complete. It's time since last timestamp.
So something between fstat and writev took 11282054 microseconds.
Ok, I recompiled the mount.exe program with -ggdb. The delay was in on
line 382. The last call to getmntent (the one that returns NULL) is the
one that takes > 10 seconds.
Was hoping that this would spark a thought in someone. I'll start trying
to get a debug cygwin load building to test further.
I tried to build cygwin. Ran into problems:
