bug in new LISP compiler

[DAVE.TOURETZKY(C410DT50) at CMU-10A]

The MacLisp compiler on [c380ml5p]/A tries to deletef the old .fas file.
Unfortunately, if it can't find a file to delete on the regular account,
it looks on the library account (set by the LIB command) and tries to
delete the file there.  If such a file exists, it usually is protected,
so the deletef fails and the compiler goes into a break.

The solution to this problem is simply to restrict the compiler (or
better yet, the deletef function itself) from looking on the library
account if one is specified.  Of course, functions such as uread and
fasload should still use the library.
