I didn't completely fix this until last night.  The message about "perl
not working" in the cygwin mailing list (which, for some reason, quoted my
cygwin-developers announcement) pointed out another impure_ptr problem.
Luckily this should was solved by making changes in the DLL.

I did (try to?) fix another libcygwin.a problem that Eric Fifer reported
last night, though, so everyone should update to that.

I agree with this.  I have been stripping the binaries and DLLs that
I distribute.  I think that if a problem happens to a person who
understands about symbols they should be able to rebuild everything
and debug.  Otherwise, we're just taking up disk space.

This does, of course, run counter to Cygnus's (and, I belive, Red Hat's)
standard way of doing things but then call me a maverick.

Note for the uninitiated:  The next step in this discussion is to point
out that "disk space is cheap nowadays and more and more people have
high speed internet access".  This is then followed by the argument
"Well, I'm running on a 33MHZ 486 with a 300MB and I'm using a 24K
modem.  I want everything as small as possible!"

[Not much opinion on point 2]

The source packages that I provide don't do this.  Probably some others
do.  I think that the 'src' is extraneous and should be removed.
