[poppler] make test fails: perf-test.cc "ambiguates old declaration"

[John L. Poole]

I am trying to build poppler-0.20.2 on Windows 7 using MinGW32 (20120426).

gcc.exe (rubenvb-4.7.0) 4.7.0

My MingGW was built by selecting the minimal install and not selecting 
any compiler, then
installing the compilers from the mingw-w64project per the build recipe at
http://ingar.satgnu.net/devenv/mingw32/base.html

The main project builds, the test phase fails.  There were some warnings 
on the initial build,
I can rerun compile and post to pastebin if anyone feels they would be 
helpful.

Here's my output:

I'm guessing that using gcc 4.7.0 is bringing to light an incompatability?

Is this a bug and is there a work-around?
