This is actually more a problem of linux. Or better of the combination
of glibc and linux. Kernel and libc structures don't match like on e.g.
Keep in mind that baseunix exports the _kernel_ sigset_t, while you pass
it to _glibc_.
All the declared functions are available in baseunix, so there is no reason
for this anyway.
There is a way to recompile FPC to be based on libc instead of the kernel,
but that is only a week old.
