Hi,
I use newlib for ARM Cortex-M3.
I agree with Joel, a malloc()/free() call for each printf() is not 
acceptable for me, this would raise the risk of memory fragmentation.

Just my two cents.

Is it possible to change the BUFSIZE on the configure command line for 
newlib?

This BUFSIZE is the same used by malloc()?
I already use CFLAGS_FOR_TARGET="-DSMALL_MEMORY -D__BUFSIZ__=256"
