This is the clue! Somehow, jam does not notice that /cygdrive exists.... I
think the attached test should reproduce the problem(run with bjam -fJamfile). 
The questions are:
(i) why all tests pass for Andre
(ii) why /cygwin is missing from Jam's POV? 

The answer to the last question is simple (once I arrive at it ;-) ):

$ ls -ld /cygdrive
dr-xr-xr-x 4 0 0 0 Jan 1 1970 /cygdrive

When this date is stored in "struct stat", it becomes 0, which, forJam , means 
that the file does not exist. Specifically, line 268 of make.c has

t->binding = t->time ? T_BIND_EXISTS : T_BIND_MISSING;

I think the best way to fix this is the attached (unfortunately untested) 
patch. Opinions?

P.S. BTW, Andre, it would be interesting if you run "bjam -fJamfile" (on the 
attached file) and report the results. Output from "ls -ld /cygdrive" is 
interesting as well...
