Judging by your "make install" output (which happened to get posted in a separate thread), you're on a Solaris box. You have choosen MOTIF as your gvim GUI. Syntax hilighting looks a bit better in gvim IMHO, so you might want to try that. Well, I might aswell post my $HOME/.vimrc file too:

version 5.0
set nocompatible
let cpo_save=&cpo
set cpo=B
map! <S-Insert> <MiddleMouse>
map Q gq
map <S-Insert> <MiddleMouse>
syntax on
set background=light
set guifont=6x13
highlight Normal guibg=white guifg=black
set guioptions-=rtT

set t_me=ESC[0;0;37m
set t_mr=ESC[0;1;33;44m
set t_md=ESC[1;33m
set t_se=ESC[1;37;40m
set t_so=ESC[1;32;45m
set t_ue=ESC[0;1;37m
set t_us=ESC[1;32m

One of VIM's greatest features is the rich "online" help. It explains everything about everything. You can access it by typing :h <searchtext> in command mode.
