[Bug-apl] Docn re Makefile & Makefile.incl & really minor typo

[Peter Teeson]

If I svn co GNU apl I get a directory of “the whole package”.
At the base level is a file named Makefile.
(really minor typo line 2 “build” sb “built”)

Examining that file indicates, on line 2, that there is  another file, 
Makefile.incl,
which includes targets that can be built without running ./configure.
On line 45 one of those targets is .PHONY: gprof.

But that target is not listed in the Makefile file. Should it be?
All the other targets in Makefile.incl are listed in Makefile.

(After running ./configure the contents of Makefile have been replaced)
