This makes it possible to use "vanilla" glpk for sage and shouldn't affect anything else.

|
# This feature allows the exact simplex solver to use the GNU MP
|

# bignum library. If it is disabled, the exact simplex solver uses the
|
|
# GLPK bignum module, which provides the same functionality as GNU MP,
|
|
# however, it is much less efficient.

# GLPK makes it possible to customize its message printing behaviour. Sage
|
|
# does that and needs to differentiate between printing regular messages and
|
|
# printing errors. Unfortunately there is no way to tell and glpk upstream
|
|
# rejected this patch. All it does is set the variable pointing to the error
|
|
# file back to NULL before glpk calls abort(). In sage's case, abort won't
|
|
# actually be called because the error handler jumps out of the function.
|
|
# This shouldn't affect everybody else, since glpk just calls abort()
|
|
# immediately afterwards anyways.
|

# See the sage trac ticket for more details:
