On the list of possible future projects for soft-fp in GCC
http://gcc.gnu.org/wiki/Software%20floating%20point
the problems with having soft-fp in both GCC and glibc are
discussed. My suggested solution involves a GCC configure
option --with-libc-soft-fp=glibc2.4 which causes the given
set of soft-fp functions to be omitted from libgcc. The
version number is needed since 2.4 has more such functions
than 2.3, and something may also need to be done to get the functions
exported from glibc (as of an older glibc version, various
soft-fp functions ended up hidden, apparently because of
libgcc-compat.S, rather than exported from the shared libc).
