Re: [Help-glpk] Patch to configure a reentrant version of GLPK

[Heinrich Schuchardt]

I would have preferred to use AX_TLS directly. But you correctly
identified that the macro does not check for _Thread_local defined in
ISO/IEC 9899:2011.

So I have now sent a patch to the upstream maintainers:
http://savannah.gnu.org/patch/?9201

Best regards
