Patch by Larry Doolittle to allow out-of-source builds of ABC. 

Usage:

Starting from an empty directory:

(1) set AS to point to the location of ABC

(2) reconstruct the directory structure of ABC in the new directory:

    mkdir -p `cd $AS && find src -type d`

(3) Build ABC:

    make -f $AS/Makefile VPATH=$AS ABCSRC=$AS
