c99 compliance

c99 compliance

[Kip Macy]

In trying to bring freebsd up to date with -unstable I hit the following:


kmacy@bldf2 make kernel

Stop in /amd/ayr/vol/users2/home/kmacy/xen/050322/xeno-unstable.bk/freebsd-5.3-xenU/i386-xen/compile/XENCONF.

Compiling without -std=c99 works ok. Would it be reasonable to ask
that we stick -std=c99 into the makefiles?
