Notes on gom's GNU autoconf "./configure" script:"
The command line interface is always compiled in. All gomiis are on
by default. These defaults can be changed using --[[en|dis]]able-*
(see "./configure --help"). The defaults are auto-deselected by
"./configure" if the needed libraries can't be found.
Remember that you need to do "make clean" if you reconfigure, but
have successfully compiled before with other options (else make won't
recompile); if you change your system's configuration, you might need
to run "make distclean" first, then rerun "./configure".
KNOWN BUGS: Essential warnings are produced, but they are not
complete (i.e. gom might still fail to compile even without
warnings). Gom basically is designed compile on a POSIX.1 system with
a C library conforming to ANSI C. GNU extensions are welcome, and used
if appropriate. At the moment, I knowingly use the GNU extensions
[v]snprintf _without_ patch for non-gnu systems. Maybe I still
unknowingly use some other GNU extensions.
