Hi Folks:  What I am striving to do is build a software based speech
synthesizer into a linux driver.  It is a greatly hacked version of
rsynth I call tuxtalk.  My problem is that I have the code so far cut
down to about 66k without the shared library routines.  When I
staticly build the object comes out to over 512k.  Obviously this is
to large to want built-in to the kernel.  The majority of the size is
from libm.a.  There are five functions I need from the library, log(),
log10(), exp() cos() and sin().

My questions are:
Are these functions which are supplied by the FPU?  I've looked
through the fpu emulation headers and exp() is the only one I can find
any reference to.

Is there a better method to provide these functions than to pull them
out of libm.a?

I appreciate any suggestions or recommendations people may have on
these questions.

  Kirk
