[R-pkg-devel] Cran submission - warning with windows (cpp build library gmp)

[Antoine Lucas]

Dear all

I would like to update gmp package - this package link to a c++ library gmp.

But windows c++ compilation warns at:
 d:/Compiler/gcc-4.9.3/local330/include/gmp-x64.h:140:23: warning: ISO
C++ 1998 does not support 'long long' [-Wlong-long]

I have not this warning on linux.
On my computer I build latest version on gmplib, and header is a
little different and should not define a long long. I wonder if the
warning could be fixed by an update of external c++ library gmp.

How could I fix my package in order to pass the cran submission ?

Regards,

Antoine Lucas
