# Please do not use here neither any special make syntax nor any unusual tools/utilities!

# using ICC compiler:
# make -f makefile.unix CC=icc CFLAGS="-O3 -xP -ip"

# using Borland C++Builder:
# make -f makefile.unix CC=bcc32

#The following can be overridden from command line e.g. "make -f makefile.unix CC=gcc ARFLAGS=rcs"
