I know next to nothing about bc and what GNU extensions are used by
timeconst.bc, but being able to build a linux kernel sounds like a
good goal to me. However, if timeconst.bc can be changed to use only
portable features of bc (in a way that is acceptable to upstream), I
think that would be better than implementing the GNU extensions.
Currently sbase (and GNU make/bc) is almost sufficient for building
linux, except for
- Usage `-n` flag in ln(1), which I think we should add.
- Usage of `\t` in sed bracket expressions. I sent a patch and it was
accepted, so this should be fixed in a future linux version (maybe
4.17?).
- Usage of `stat -c "%s"` to determine file size. I sent a patch to
use `ls -dn`, but still need to respond to some comments.
