Not everyone runs his programs from a shell. Apart from that, there are
a bunch of security- and consistency-issues linked to that.
wine kinda pisses of with its hundreds of env-options, but just consider
having one set of commands for each little suckless tool around.

A central config.h and command line arguments are definitely enough.
If you still want to set according to env-vars, you might want to
define a var for each program and invoke it with "program $VARSET",
where $VARSET is the set of command-line-options you have set before.
