cannot compile graal with gcc 6.1 on 64bit linux and jdk 8u92

[Tortonesi Mauro]

Dear all,

sorry to bother you again, but I really can't get Graal to compile
with Arch Linux 64bit, GCC 61, and JDK 8u92. I keep getting C++11
compilation problems such as:

/home/mauro/code/git/graal/jvmci/src/share/vm/gc_implementation/g1/g1BlockOffsetTable.inline.hpp:55:37:
error: invalid suffix on literal; C++11 requires a space between
literal and string macro [-Werror=literal-suffix]

          err_msg("Index "SIZE_FORMAT" corresponding to "PTR_FORMAT
         \

                                     ^

                                 ^

even when using:

CXXFLAGS="-O2 -std=c++0x" mx --vm server build

(Disclaimer: I am not familiar with mx. FWIW, it might just ignore the
CXXFLAGS environment variable.)

Could you please give me some advise on how to fix this? I would very
much appreciate it!


Best regards,
Mauro Tortonesi
