Thank you Andrew for kind feedback!
I will go back to wiki first about these related mailing lists.
Yes im working on cross-compiling for linux specific target machine and gnu
ld linker is preferred by default; will find out otherway for compatibility
with various systems likd macOS ld or Solaris ld.

Sure will go back to read mpc extensions based on mpfr/gmp.

This sounds great! will try to put them on toplevel src directory tree.
