    commit 97015a07

        dix: integer overflow in RegionSizeof() [CVE-2014-8092 3/4]

offended the C++ demons:

../../include/regionstr.h:147:45: error: invalid conversion from 'void*' to
'pixman_region16_data_t* {aka pixman_region16_data*}' [-fpermissive]

Normally this isn't a problem, because around here we have the sense and
common decency to not use C++, but this does make tigervnc fail to build,
which is a little rude of us.
