For me `echo TEST | busybox tr '[:upper:]' '[:lower:]'` seems to work correctly. Maybe character class support was added to busybox tr?

> Maybe most people use very old versions of BusyBox. Ether **very** old versions or they have disabled `ENABLE_FEATURE_TR_CLASSES`. Character classes have been added in 2005... https://git.busybox.net/busybox/commit/?id=f1048143ee4360affc66c39961f7862ea914400d

Or would it be better to set a default for --config-file?

Aside from a segfault in the test suite this seems to fix the qsort issue: ```patch --- a/stellarsolver/astrometry/include/astrometry/ioutils.h +++ b/stellarsolver/astrometry/include/astrometry/ioutils.h @@ -28,17 +28,12 @@ #include "astrometry/an-bool.h" #include "astrometry/bl.h" #include "astrometry/keywords.h"...

Also the removal of code from `os-features-test.c` broke automated test completely since test compilation now always fails with ``undefined reference to `main'``: https://github.com/rlancaste/stellarsolver/pull/139/files#diff-ab098867e3d6840103789db63646fa629a1558eecee4fc3d9284dfbf4d93756a

Looking at #139 it seems to me that it broke more things than it fixes

This could may be fixed by making the 'Int` joker type correspond to the `int64` go type. It shouldn't matter for 64-bit systems and would make sure that 32-bit systems...

Is this still stuck in review?
