Description
When building spice-gtk with modern gcc, the tests fail to build with the following error below.
I've tried various combinations and modifications to the tests/Makefile.am to explicitly add -lm to LDADD, AM_LDADD, AM_LIBS, etc, and was still unable to come up with a working patch, not sure what's going on here.
