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
