Bug#798288: x11-xserver-utils failed to build with gcc 5
Package: x11-xserver-utils
Version: 7.7+4
Severity: serious
cpp-5 insert some comments when replace macros,
so it makes sessreg manpages fail to build.

GCC may insert some comments everywhere when replace placeholders.
GCC 5 just does it here.
