* Set the format style used by gcc to check printf type functions. We really
* want the "gnu_printf" style set, which includes what glibc uses, such
* as %m for error strings and %lld for 64 bit long longs. But not all gcc
* compilers are known to support it, so we just use "printf" which all
* gcc versions alive are known to support, except on Windows where
* using "gnu_printf" style makes a dramatic difference. Maybe someday
* we'll have a configure test for this, if we ever discover use of more
* variants to be necessary.
