Hi Stephen, I still don't have it running. There was a garbage collection event
while I made sure I didn't have unpaid income taxes by midnight, April 15th.

Deleting a lot of information from my previous email:

Here is a clue:
If the CWD is "x" and I ask of Cygwin (latest version from ANL),
"ls x," where "x" does not have a proper initial string of "/cygdrive/d,"
then Cygwin replies "No such file or directory exists." I reinstalled
Cygwin shortly before installing MLton because I thought Cygwin's
behavior was strange in regard to "ls." This Cygwin was a fresh
download, too.

After (necessarily) prefixing "lib" in "mlton" with "/cygdrive/d," and
prefixing Cygwin CLI filestrings with "/cygdrive/d," I get the following:

Yes, that's what happens.

Administrator /cygdrive/d/usr/local/bin
$ /cygdrive/d/usr/local/lib/mlton/mlton-compile @MLton load-world /cygdrive/d/u
sr/local/lib/mlton/world.mlton --
sread failed (error 0)

Administrator /cygdrive/d/usr/local/bin
$ strace /cygdrive/d/usr/local/lib/mlton/mlton-compile @MLton load-world /cygdr
ive/d/usr/local/lib/mlton/world.mlton --
strace.exe: error creating process 
/cygdrive/d/usr/local/lib/mlton/mlton-compile
, (error 3)

Here we have new information. What does it mean?
