I am attaching a patch to R-0.63's configure.in file which will enable
R to detect and use some special math libraries on linuxppc and mklinux.
The patch provides tests for these libraries and enable/disable switches
for them as well.
One library is the libmoto math library which must be used in
conjunction
with libm (it only replaces some of libm's functions). The other is a
RISC optimized BLAS library, libblas_risc, which must be used along with
a standard implementation of BLAS, libblas. It only provides optimized
versions of GEMM routines for single and double precision real values.
Please let me know if the tests cause problems on other architectures.
