build error with intel c compiler (c++11)

[htower]

I've been trying to compile your library with intel c compiler and -std=c++11 flag enabled:

format.cc(55): error: more than one instance of overloaded function "signbit" matches the argument list:
function "signbit(double)"
function "std::signbit(double)"
argument types are: (double)
return signbit(value);
^

compilation aborted for format.cc (code 2)

$ icc -v
$ icc version 14.0.2 (gcc version 4.6.0 compatibility)

with -std=gnu++98 (default) everything is good.

Fixed in f2e0680. Thanks!
