Thanks for patching this! I was mainly concerned about the
unpredictability when starting different programs ending in .exe.
I didn't know that it was (before your patch) by design. But i like
the new design better ;)

I found another variation of my testcase showing that the failure
in the path hashing also happens in directories with less files
and that it doesn't "disable" the hashing for those directories
completely.

Unpatched standard cygwin tcsh:
[quetschke@Macros ~]$ which gcc.exe
/usr/bin/gcc.exe
[quetschke@Macros ~]$ which whoami.exe
whoami.exe: Command not found.
[quetschke@Macros ~]$ which whoami
/usr/bin/whoami

This doesn't "feel" like a cygwin bug, but cygwin's tcsh
makes it easier to find it. I'll try to write a consistent
bug-report to the tcsh people.

Thanks
