Can you look in config.log, and see why configure seems to think that

it is indeed set to 0. Searching for HAVE_STRUCT_SCHED_PARAM in config.log
reveals a single line only, so i don’t know where it is set and why.

I think here’s a relevant part of the log:

p.s. Not sure if config should actually use anything from `/usr/include/sched.h` as I compile with GCC, not Clang. M4 compiles fine with apple's Clang.
