Those who are doing numerical simulations need speed, memory and accuracy. DJGPP
delivers speed and memory. Increasing the numerical precision may e.g.
reveal possible
cancellation errors and therefore be useful for development of the
algorithm. If no
cancellation errors are present, one may continue to use good old double
precision.
One should have a look at the increase in code size, both in scanf and printf,
after compression. If the code size of the hello world app is important,
include in the distribution a hello world.c with puts instead of printf.
What we see here is the burden of the run time evaluation of the printf format
instead at link time, nothing to be done about it.
Imagine DJGPP obtaining higher ratings on Moshier's test bed IEETST than
commercial stuff ? DJGPP is not only used for Quake....
