Log message:
Changes 4.44:
The following suffixes for variables and constraints were
implemented in the MathProg language:
.lb (lower bound),
.ub (upper bound),
.status (status in the solution),
.val (primal value), and
.dual (dual value).
Now the MathProg language allows comment records (marked by
'#' in the very first position) in CSV data files read with the
table statements. Note that the comment records may appear only
in the beginning of a CSV data file.
The API routine glp_cpp to solve the Critical Path Problem was
added and documented.

Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Log message:
Changes 4.34:
* The GNU MathProg modeling language was supplemented with three
new built-in functions:
gmtime obtaining current calendar time
str2time converting character string to calendar time
time2str converting calendar time to character string
* For detailed description of these functions see Appendix A in
the document "Modeling Language GNU MathProg", a new edition of
which was included in the distribution.
* A bug was fixed in the MIP solver.
* A new makefile was added to build the GLPK DLL with Microsoft
Visual Studio Express 2008 for 64-bit Windows.

Log message:
Changes 4.33:
* New API routines
* A crude implementation of CPLEX-like interface to GLPK API was
added to the package. Currently it allows using GLPK as a core
LP solver for Concorde, a well known computer code for solving
the symmetric TSP.
* Some bugs were fixed in the SQL table driver.
