Please see the attachment (oldapi.tar.gz). Files lpx.h and lpx.c
implement the old glpk api (as it was defined in glpk 4.48) thru calls
to the new api routines. To compile an existing project you need to add
to it these two files. File lpxsamp.c is an example that illustrates
using the old api. Please note that these three files will be included
in a next release of the package. Thanks.
