More patches from Erik van der Wal, these to deal with errors when using
disable-double-buffer, when using the non-Tcl version, and a segfault on
color change.

Removed AM_C_PROTOTYPES from configure.in on a tip from Randy DuCharme;
it appears that this automake function is no longer supported, and some
gnu developer doofus made aclocal die with an error on encountering it
rather than flag a warning and continue.
