A while back, I changed the namings to conform to the autoconf
documentation[1], which basically says that --with[out] controls the
use of external features/libraries, while --{en,dis}able controls the
use of features provided by the package.

[1] and to be consistent with other packages' configure scripts.

So, the following are controlled by --{en,dis}able:

  --enable-sysv           define the compiler macro SYSV
  --enable-another-button use two-button mouse conveniently
  --enable-socket         use socket XDriver (default)
  --enable-fifo           use FIFO XDriver instead of sockets
  --enable-w11            use W11 library for Windows X11 emulation

Everything else (i.e. library dependencies) uses --with[out].
