Log Message:
Changes 4.54:

Block-triangular LU-factorization was implemented to be used
on computing an initial factorization of the basis matrix.

A new version of the Schur-complement-based factorization
module was included in the package. Now it can be used along
with plain as well as with block-triangular LU-factorization.

Currently the following flags can be used to specify the type
of the basis matrix factorization (glp_bfcp.type):

GLP_BF_LUF + GLP_BF_FT   LUF, Forrest-Tomlin update (default)
GLP_BF_LUF + GLP_BF_BG   LUF, Schur complement, Bartels-Golub
                         update
GLP_BF_LUF + GLP_BF_GR   LUF, Schur complement, Givens rotation
                         update
GLP_BF_BTF + GLP_BF_BG   BTF, Schur complement, Bartels-Golub
                         update
GLP_BF_BTF + GLP_BF_GR   BTF, Schur complement, Givens rotation
                         update

In case of GLP_BF_FT the update is applied to matrix U, while
in cases of GLP_BF_BG and GLP_BF_GR the update is applied to
the Schur complement.

Corresponding new options --luf and --btf were added to glpsol.

For more details please see a new edition of the GLPK reference
manual included in the distribution.

A minor bug (in reporting the mip solution status) was fixed.

A call to "iodbc-config --cflags" was added in configure.ac
to correctly detect iodbc flags.
