> There are several portability problems preventing from compiling native 
> component on freebsd.
> 1. libgen.h is not included. correct function prototype is there but linux 
> glibc has workaround to define it for user if libgen.h is not directly 
> included. Include this file directly.
> 2. query max size of login name using sysconf. it follows same code style 
> like rest of code using sysconf too.
> 3. cgroups are linux only feature, make conditional compile and return error 
> if mount_cgroup is attempted on non linux OS
> 4. do not use posix function setpgrp() since it clashes with same function 
> from BSD 4.2, use equivalent function. After inspecting glibc sources its 
> just shortcut to setpgid(0,0)
> These changes makes it compile on both linux and freebsd.
