[pygsl-discuss] Intel compiler issue with const

For info:

I recompile pygsl with the Intel Compilers for Linux and run into one
problem with pygsl.const and the optimizer.  When compiled with
optimization pygsl.const crashes with SIGSEGV in add_constants().
Turning of optimization for this file (src/constmodule.o) or changing
it like the following diff fixes this.

No big deal, but we could put a note into the README that states that
src/constmodule has to be compiled without optimization when using icc
for Linux.

If somebody knows how to report bugs for the personal version of icc
to Intel please let me know.

Greetings,
Jochen
