# Excerpt from glpk's INSTALL file:
# 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:
