Patch from Aaron Lehmann <aaronl@vitelus.com>;
This diff does 2 things:
1) removes an unnecessary function. saves 64 bytes on i386
2) allows you to disable checking of mail (actually, it's now disabled
by default). this would be a nice CML1 option, but for now it's a
#(define|undef) in the C file like the other internal ash options.
this saves an additional 352 bytes if you leave mail disabled.
