libXpm supports two optional features to handle compressed pixmap files.

--enable-open-zfile makes libXpm recognize file names ending in .Z and .gz
and open a pipe to the appropriate command to compress the file when writing
and uncompress the file when reading. This is enabled by default on platforms
other than MinGW and can be disabled by passing the --disable-open-zfile flag
to the configure script.

--enable-stat-zfile make libXpm search for a file name with .Z or .gz added
if it can't find the file it was asked to open.  It relies on the
--enable-open-zfile feature to open the file, and is enabled by default
when --enable-open-zfile is enabled, and can be disabled by passing the
--disable-stat-zfile flag to the configure script.
