GraphicsMagick *and* ImageMagick fail to compile

[Walter Schwarzenfeld]

First:
what is in /etc/make.conf ?
-----
try compile it with GCC
either
withe GCC=    4.8+
in the Makefile
or
with CC=gcc48 CXX=g++48  CPP=cpp48
(you can use gcc48 or gcc49 or gcc5)
------------------
I had a similar error with irc/hexchat
(it compiled only with GCC not with clang).
add to the Makefile

MAKE_ARGS=    LDFLAGS="${LDFLAGS}"

solved my problem.
