Subject: can't run cygwin emacs or XWin Server
Message-ID: <914c7a91-da0d-5102-f884-3fe0deba5bf3@onetel.com>

I run 32 bit cygwin on a 64 bit machine running Windows 7.

I used to get an XWin Server terminal running bash at startup (logging 
into Windows) from which I could run the emacs packaged in cygwin.  
After a round of updates I don't get the terminal window at startup and 
if I try to manually launch it it fails to launch and AFAICT if I try to 
run emacs from a command prompt I get the native version of emacs that I 
also have installed and not the cygwin one.  The shortcut for XWin Server is

    C:\cygwin\bin\run.exe /usr/bin/bash.exe -l -c /usr/bin/startxwin.exe

This seems to me to be the "phantom /usr/bin issue" mentioned at 
www.postgresql.org/message-id/blngoc%24nrr%241%40sea.gmane.org because I 
get the same behaviour described there and in related posts.  I have 
verified that "/usr/bin" and "/bin" are the same as far as ls is 
concerned.  The relevant part of the path as shown in System Properties 
 > Advanced > Environment Variables is "C:\cygwin\usr\bin;C:\cygwin\bin" 
which precedes 
"C:\Users\Mike\Downloads\emacs-25.1-2-i686-w64-mingw32\bin" in the path 
which is what ends up running.

However if I run the MS shell in emacs or use command prompt then "which 
ls", "which bash", "which emacs", "which printenv", "which startxwin" 
and "which which" all come back with "/usr/bin/..." so those are 
recognised by which at least.

I hope I'm just missing the obvious.  Thanks for any help

Merry Christmas
Mike
