For mcs51 there are several printf functions. Perhaps you might try
using printf_tiny. For example, near the top of your code, use
#define printf printf_tiny
A table was recently added to the SDCC manual showing the difference
between the various printf functions.
Also, I'd suggest you avoid using --stack-auto unless absolutely
necessary. As Maarten pointed out, the library needs to be recompiled.
SDCC produces far better code using the default --model-small without
reentrant functions.
