I've been having some issues with the OpenEXR libraries (as mentioned on
the Ports list), and it looks like the problem is in ilmbase. I have
attached the .cygport and a build patch; it has no dependencies besides
a C++ compiler. Neither Debian nor Gentoo ship any patches for ilmbase,
so I'm suspecting a bug in either Cygwin or GCC.
After building a debug build and running 'make check' in IexTest:
$ ../libtool --mode=execute gdb ./IexTest.exe
[...]
(gdb) run0
