Compiling with gcc-4.7 (Re: Can't build cairo on HEAD

[Makoto Fujiwara <makoto%ki.nu@localhost>]

Hi,
I have some reason to use gcc-4.7.
So I've setup for NetBSD/amd64 6.1_RC2 with gcc-4.7 compiler.

With this environment, I got the same error on cairo-1.12.14nb1.

 +------------------------

And I have work around for this point as attached below.  With
these work around, I get another problem as:
 +------------------------
 | .libs/cairo-arc.o: In function `gets':
 | cairo-arc.c:(.text+0x6c0): multiple definition of `gets'
 | .libs/cairo-analysis-surface.o:cairo-analysis-surface.c:(.text+0x350): first

 | .libs/cairo-analysis-surface.o:cairo-analysis-surface.c:(.text+0x360): first

 +------------------------

I don't think this can be resolution anyway, but just FYI:
