Merge: Regen c_src without libunwind

The last `c_src` is 3 month old, it seems to be usual to have 3 to 4 months between updates.

This update also did not depends on libunwind: so no stacktrace but can compile on rasperry pi. so fix #1149
Note that the following steps of the initial make will still implicitly include libunwind, so on raspberry, either do the next steps manually with `--stacktrace none` or edit `src/Makefile` to add `--stacktrace none` to both `NITCOPT` and `OLDNITCOPT` (at the begin of the file)
