Unfortunately this is not (yet) true for the pic16 targets to which you
were referring. Outputting float values was just not implemented in the
pic16-printf() routines, so recompiling would not have helped.
I just (svn r5371 and a fix in r5373) added support for float output to
pic16-printf(), but disabled it by default as with most other targets to
keep code size down for the majority of users (not using floats). You can
enable it by adding --enable-floats to the ./configure-call in the
device/lib/pic16/ directory when building sdcc from source. The
sdccman.lyx file is also updated with instructions to enable float support
when building the libraries.
Please try tomorrow's snapshot or the current svn revision and report any
problems occurring in the process (it works for me both with and without
float support, but who knows...).

Wow, you were able to use sprintf from the pic16 library?!? I also just
committed some fixes to the way stringbuffers are handled: Prior to these,
the pointer passed into sprintf would be modified by the
strmputchar()-routine to always point to the terminating 0 byte... Maybe
using a global buffer instead of a local pointer saved your day so far...
Again, any feedback on success or failure with sprintf/fprintf/... is
highly appreciated, especially before the upcoming release!
Thanks for reporting your problems.
Best regards,
Raphael
