This version removes a few subtle, but rare bugs. It also makes all
shell scripts completely POSIX-compatible by removing the use of
`local`. It also adds locales, but since Alpine does not have a
replacement for gencat, I can't enable that support. The `-N` option
given to configure.sh turns off locale support.
The APKBUILD author probably intended to conflict with `main/bc` while
providing a `bc` meta package at the same time. Unfortunately, doing so
would require `main/bc` to be renamed. Otherwise this package is
uninstallable since it conflicts with itself.
This commit makes this package installable by not providing a `bc` meta
package. The alternative solution, renaming `main/bc`, would have been
too intrusive.
