I realize what you say, but on the other hand, the mount stuff kind of lives in the transition zone between Win32 and the rest of Cygwin. Look, those are Win32 paths on the left, and the theory I gave is reasonable, even if untrue. :) However, I did later notice another problem. After believing my theory, and reinstalling to c:\cygwin, the error kept occuring. (Oh, and yes, I stuck strace into the configure file). Finally I remembered, that after the original problem, and noticing that the gcc tree is apparently setup to build a bunch of stuff all together, not just gcc, binutils, gmp, mpfr, but a bunch more, including flex, I stuck the flex source in there as well. Figuring I'd maybe build and debug it.Well, it appears the gcc's support for integrating flex is actually not working. Configuring binutils decides to run a flex that doesn't yet exist, if the source is there. Looking in . and looking where configure thinks flex will be, while perhaps different by a path element or two, to the very lazy/casual/careless/Jay observer -- same thing. SO, I've deleted the flex source, and reinstalled to c:\cygwin, and I'll punt this for now. I have symlinks /c = /cygdrive/c, /obj = /c/obj, etc. At some point I should go back to c:\ (or d:\, whatever), keep flex source out, and see what happens. I still think my theory is close to correct, but I probably polluted the repro case before the later debugging, oops. I'm sure I didn't put the flex code there until after I first had some problem.

Re: flex: exec failed? (root install/mount)
As a follow-up and clarification to my previous post, what I would like to be able to do is to pipe output to a printer, e.g. ls -l | lpr This doesn't work for me as I explained previously. Using notepad /P I'll bet it doesn't! From the lpr manpage: No formatting is done -- data is sent raw. This means your printer has to understand *raw* text, which is what the 'ls' command generates. Many printers can do this, but U'll probably have to play with driver setup to make it work. BTW, I didn't see this thread on gmane yet, so I just started it over. I apologize for messing up threading, but I just *had* to reply.

I tried unmounting it and explicitly mounting d:\, d:\\, d:/, but they still all got treated as d:. Tried editing the registry, same thing. Used d:\foo also to make sure what I was doing was being seen by the code. Another way to achieve what I want is for d:\cygwin to be an NTFS junction do d:\, but then I have circularities in my file system, which I'd rather avoid. I know installing to the root is discouraged, but..agreed this is a bug? Should be fixed? It is easy to fix? I think so, on all counts. I'm sure I can provide a patch. The /cygdrive mounts must deal with this specially?? - Jay From: [EMAIL PROTECTED] To: cygwin@cygwin.com Subject: FW: flex: exec failed?
