Created attachment 174566 [details] add patch file to remove fpsetround use in tcl fpsetround is non-standard and is not provided on arm64 or riscv. On other architectures where fpsetround does exist, fpsetround(FP_RN) just sets the rounding mode to the already-set default, so it serves no purpose.

I took the liberty to fix tcl84, tcl85 and tcl87 too.
