Yes I agree. It works with the stock bash.exe, but not with the one I've
just rebuild.

Here are some results: because of the value of SYSROOT being "C:",
dosutil_expand_path expands /dev/null to c:/dev/null.
Then a call to 'open' is performed with "c:/dev/null" as first argument.
It is this call which fails.

A little test program easily shows that 'stat' and 'open' effectively fail
with "c:/dev/null" but not with "/dev/null".

As I do not have the patched sources of open and stat, I cannot make
further investigations. Nate, could you please send them to me, or at
least tell me where to find them ?
 
Olivier.
