Hello Mike !
I did changed in several places see here
https://github.com/mingodad/GLPK/commit/b370a854be0c10c06e025896dedc4e3461278497
===
Changed some declarations to glp_long_double in hope that using it on
mainly "sums" would improve performance/accuracy, but right now
performance decreased, hashi.mod takes too much time, but defining
glp_long_double as glp_double we still have the same results/output as
the original GLPK
===
Cheers !

I just got glpsol with "long double" working and add binaries for
anyone that want to test then here

As noted there it'll benefit from tuning the constants in
src/glpk_real.h
Any help/suggestion/comment is welcome !
Note that using long doubles everywhere
would slow down a memory bound computation.
Fetching more data would be required.
One might introduce glp_double_t.
C99 uses double_t for the type in which unnamed
intermediate results of double calculations are stored.
Use glp_double_t for locals that are not arrays,
especially running totals.
Do the casts to ensure that desired calculations
are actually done in glp_double_t.
