Re: Try experimental GMPL extensions online

[Domingo Alvarez Duarte]

Hello Karl !

Thank you for reporting it !

It was an assertion with side effects that I missed on my previous 
review, here is the fix 
https://github.com/mingodad/GLPK/commit/0f925bfc17540e771c1bbcd83f233f8fdc772752 
, I also updated the online https://meimporta.eu/myglpk-ext.

One thing still reamain to be fixed, I noticed that the online glpsol 
solves the hashi.mod a lot faster with the "--cuts" parameter but on my 
branch https://github.com/mingodad/GLPK/tree/local-set-param the native 
glpsol is not as fast the online version (it's a lot slower).

Cheers !
