Hello:
Thanks if someone can help me with this issue.

I´m using eclipse neon with cygwin and googletest and gnu++11. Also working with strings. But when I build the code, It haves 2 errors:

g++ -std=c++0x -std=gnu++11 -D#_GXX_EXPERIMENTAL_GNUXX11_ -O0 -g3 -Wall -c -fmessage-length=0 -std=gnu++11 -MMD -MP -MF"tests/tests.d" -MT"tests/tests.o" -o "tests/tests.o" "../tests/tests.cpp"
<command-line>:0:1: error: macro names must be identifiers
make: *** [tests/subdir.mk:20: tests/tests.o] Error 1

A macro name must be a C or C++ identifier.
Remove the '#" in the macro definition for _GXX_EXPERIMENTAL_GNUXX11_ to make it a legal identifier.
It may be automatically defined by -std=gnu++11 thus unnecessary but I don't have time at the moment to look it up.
