[PATCH] Remove lnx_font.c and lnx.h

Sun Nov 1 12:22:44 PST 2009
I couldn't find any version of the X xserver that ever used lnx_font.c
so let's delete it. I tried contacting its author, Egbert, multiple
times on IRC and email [*] but never got any response. It also hasn't
been seriously touched since January 2005.
