Tasking and stack space usage by printf on Sun 3

[neal at druhi.att.com]

Warning - the Sun 3 implementation of printf (and fprintf, sprintf) uses a
large amount of stack space - over 2000 bytes in normal usage.  When you
use the %f format for floating point, the usage goes up to over 20000
bytes!

This may not matter a lot in most situations, but when you are managing
multiple tasks, e.g. using the C++ task library, you need to allocate lots
of space for the stack frames.  (The default is 3000 bytes.)

This is true for at least the 4.0 release of SunOS on a Sun 3.  Does
anyone know if this is true in 4.1, or on the SPARC implementation?  Does
anyone have an alternative implementation of fconvert(), etc?
