Xpm enabled NTEmacs hangs if your %PATH% includes cygwin\usr\X11R6\bin.
LoadLibrary("libxpm.dll") never returns in w32_delayed_load() in
src/image.c.
Since the most cygwin DLLs are not meant to be loaded by non-cygwin apps
(if you do, they hang),
I suggest we simply remove "libxpm.dll" and "libXpm-nox4.dll" from
image-library-alist.
(AFAIK Emacs on Cygwin does not use this variable.)

It is better not to have a cygwin binary directory in Emacs' PATH. If
you don't want to mess the system or user PATH variables for Emacs,
you can define your own PATH variable as a value in the registry (in
key HKLM\Software\GNU\Emacs), and Emacs (the Windows port, at least)
will obey it.

libxpm.dll and libxpm-nox4.dll are not "cygwin DLLs". There are
MinGW-compiled versions of both.
You can also modify `image-library-alist' in your path. There's no
need to change the default value.

Thanks.

It may need a special notice about this when you distribute xpm-enabled
NTEmacs binaries.
I know a few users who get into this trouble.

This does not work when I do "make bootstrap".
I will do the registry thing. Thank you for information.

Perhaps it would be worth noting it somewhere, but the trouble is not
Emacs-specific. Other MinGW-built free software using image libraries
could fall in the same trap.

True. This could be circumvented with "make PATH=... bootstrap", but
again, it is best not to have Cygwin in the path (or, at the very
least, not before the Emacs binary directory) unless needed.

Yes, you're right. I misremembered that Emacs looks for HOME. Sorry.

It does not work.
Quick look at init_environment() in w32.c, it seems Emacs does not look
for PATH.
Anyway, I can overcome the problem on my own, just end users' sake.
Thanks.
