# GNU and BSD bc's have slightly different behavior. This bc can act
# like both, changing at runtime with environment variables, but it
# needs defaults, which can be set at compile time. This option sets all
# of the defaults to match the GNU bc/dc since it's common on Linux.

# A lot of test results are generated first by a bc compatible with the
# GNU bc. If there is no GNU bc installed, then those tests should be
# skipped. That's what this option does. Without it, we would have a
# dependency cycle. Those tests are super long, anyway.
-G
# Disables the automatic stripping of binaries.
-T
# Enables installing all locales, which is important for packages.
-l
# Disables some "problematic" tests that need specific options on Linux
# to not trigger the OOM killer because malloc() lies.

# This is to fix a bug encountered on Arch. It is to ensure we don't get
# segfaults on `make check` when the error messages change because the error
# messages are passed to printf(); they have format specifiers. With these
# env vars, the internal error messages are used, instead of the installed
# locales, which might be different since the new locale files are not
# installed yet. (It is impossible to use uninstalled locales because of the
# poor design of POSIX locales.)
