# "configure" for ampl/solvers/snopt
# Originally written by David M. Gay at Sandia National Labs, where it
# was Approved for Unclassified-Unlimited release: SAND Number 2005-7812P
# Modified to permit "path/to/ASL/snopt/configure" invocations.

## invoke ./configure
## (no args) to make system-dependent files in directory $OBJDIR
## (default sys.`uname -m`.`uname -s`).
## Among other things, create makefile there from makefile.u.
## Specify CC before invoking to adjust the CC setting in makefile.
## Specify CFLAGS before invoking to adjust CFLAGS setting in the makefile.
## CFLAGS may be further adjusted by tests done below.
