There are a lot of #else-#if's.  For example, in Japan,

    sprintf(Buffer, "%02d.%02d.%02d", Year, Month, Date);

but really more like

    sprintf(Buffer, "%c02d$BG/(J%02d$B7n(J%02d$BF|(J", Era, Year, Month, Date);

... my apologies to those of you who can't see the characters for
"year", "month", and "day" in the above character string 'cause you're
using fascist terminals which aren't sensitive to international
character sets...

We really need a preprocessor #switch for this.

In practice, execution-time if's are more common, and they should be
but aren't execution-time switch's.

Anyway, if you want to sell your software to other locales, you will
code your software with proper sensitivities.  If you want to buy
software that someone didn't want to sell you, well, you're got a
little bit of work to do.  And if you don't want to buy software that
someone didn't want to sell you, then why worry about it?
