Well, sort of. What's actually happening is that the cc -E runs fine because
it has the -D_REENTERANT flag, but then the cc doesn't compile because it
doesn't have that flag.

I run into the opposite problem a lot when I set CFLAGS but not CPPFLAGS on
something and it autoconf will spit out "xxxx works but is not present" which
always cracks me up. ;)

OK, one more compile with CFLAGS and CPPFLAGS... ok.

Which leaves me with a few final questions:
1. Why doesn't this happen with 1.3.x?
2. Am I really the first person to run into this?

Thanks for your help.
