Hi all,
attached patches goes on top of other 6 caf_shmem coarray patches and fixes
missing includes esp. on non-Linux systems. I have tested this on a FreeBSD,
which is very time consuming due to it being fully virtualized on my system.
Regtests ok on x86_64-pc-linux-gnu and aarch64-unknown-freebsd14.3. Ok for
mainline?
Thanks to Steve for bringing these deficiencies to my attention.

Definitely much faster than mpich. I also over prescribed the number of images
to 30 and ran as well.
I still need to build OpenCoarrays using this gfortran-16 and make sure it
succeeds those tests with mpich. I will try to then test each case on the
OpenCoarrays suite of tests with -lcaf_shmem and see if those all work.
Any ideas on how to stress test this. I only have 32 gig of memory here and
would like to see how a longer running program does.

Jerry
