Debian switching to EGLIBC

I would be extremely happy if I could rely on printf not changing the periods to commas when I don't expect it, and strcmp not changing. I have to force the C locale at startup just so our software can write files that I can be sure can be read.

Any intelligent person would have just made a different %-command. It really is not very hard for a programmer to choose what to do based on the locale. The C library, if it provides anything at all, should only provide a "this is the locale" call. It should have ZERO effect on the behavior of any functions that do not actually take a locale as an argument.
