Re: Is detecting endianness at compile-time unworkable?

And, as an aside, the reason we can't easily make it better ourselves is
because the build process for git.git doesn't have a facility to run
code to detect this type of stuff (the configure script is always
optional). So we can't just run this test ourselves.

It won't help those who cross-compile anyway.  I thought we declared
"we make a reasonable effort to guess the target endianness from the
system header by inspecting usual macros, but will not aim to cover
every system on the planet---instead there is a knob to tweak it for
those on exotic platforms" last time we discussed this?
