[Bug-glpk] 2 Bugs I found

[Huegler, Peter A.]

I believe the I have found two bugs in the package.  Attached are fixes that
I have applied to the code.

1. Use of functions in assert macros.

When the programs are compiled using the NDEBUG preprocessor definition (in
a release mode), the functions within the asserts are not called.
Consequently,  the simplex routine is not initializing correctly.  Attached
are my fixes.

 <<glp_simplex.diff>>  <<glp_write_mps1.diff>> 

2. Write MPS files do not load into LINDO correctly.

The glp_write_mps routine outputs column lines with blank name fields.  This
is a problem for LINDO.  I changed the column write code to always output a
column name.
