Set to true to use the old vfprintf instead of the new. This is roughly
|
|
|
- C89 compliant, but doesn't deal with qualifiers on %n and doesn't deal with
|
|
|
- %h correctly or %hh at all on the integer conversions. But on i386 it is
|
|
|
- over 1.5k smaller than the new code. Of course, the new code fixes the
|
|
|
- above mentioned deficiencies and adds custom specifier support similar to
|
|
|
- glibc, as well as handling positional args. This will be rewritten at some
|
|
|
- point to bring it to full C89 standards compliance.
|
|
|
+ C89 compliant with some extensions, and is much smaller. However, it does
|
|
|
+ not support wide chars, positional args, or glibc custom printf specifiers.

Most people will answer N.
