Ah, I misread your earlier message and I thought you said that
gcc-4.9 worked ok and it was plain 'gcc' that caused the warning.
Is that expansion of the macro the one produced by gcc-4.9, then?

Also, you're right that we should figure out why it seems to
be using the wrong C compiler. Can you use 'V=1' to look at
what command line make is using to compile this file, please?
(you'll probably want to dump the whole make output to a file
and then search through it). Also:
*  what does your config-host.mak say (in particular about what
 it's set CC, HOST_CC, CXX, etc to)?
* can you check your environment doesn't have CC set to anything?
("env | grep CC" should tell you if it is)

thanks
