Hi,

your package FTBFS on GNU/kFreeBSD because of limits.h include issues:

Given there's already some kind of hack to fix the Linux build, I chose
to completely disable the include (see attached patch), and it then went
fine.

I guess you might want to:
 - only call #include_next if linux is defined;
 - or try and enable the hack for GNU/kFreeBSD too (you then want to
   check for __GLIBC__); I didn't try so because the include didn't seem
   needed.

If you want me to run a test build with a given patch, just ask.

Thanks for considering.

Mraw,
KiBi.
