[MiNT] nanosleep

[Peter Slegg <p.slegg@scubadivers.co.uk>]

Hi all,

I am trying to use a unit that has nanosleep in it.
I see that there is a version in mintlib

How can I add this to my make to avoid this error ?

msleep.o:obj.040/msleep.o:(.text+0x54): undefined reference to `_nanosleep'

Regards,

Peter
