Thanks for the hint, adding an include solves the issue.
It had compiled without because I have a plain extern int select() 
declaration. It's obviously not a good declaration because the pointer 
arguments can now be 64 bit. (I think I could not unconditionally 
include select.h for porting compatibility with some legacy systems that 
don't have it.)

Not sure whether it's a bug then as arguably a program using select 
should declare it properly. On the other hand this issue has not 
appeared on any other system and if traditionally include time.h used to 
imply include select.h maybe that should be maintained.
