The reduced test case.

ccc-analyzer shows me an incorrect warning using strcmp(). I've reduced the
test case to the attached file. The command line that triggers the warning is

/usr/share/clang/scan-build-3.7/ccc-analyzer -I
/usr/lib/x86_64-linux-gnu/glib-2.0/include/ -I /usr/include/glib-2.0/ -Wall
testclang.c -O2 -g -DNDEBUG -lglib-2.0 -o testclang

The test case is a reduction from the wireshark source code, where the bug was
initially found. I decided to write a stripped down version of the code to
isolate it.
