The new math.h is causing some problems.  There are big problems with
libg++.  Here is a section of my make transcript, which is pretty much
a superset of all the other compile failures.  A *LOT* of files in
libg++ have similiar problems.

g++ -fpic -DPIC -O -I/usr/src/gnu/lib/libg++/libg++ -nostdinc++ -I/usr/src/gnu/lib/libg++/libg++/../g++-include  -I/usr/src/gnu/lib/libg++/libg++/../iostream -c /usr/src/gnu/lib/libg++/libg++/Complex.cc -o Complex.so

*** Error code 1 (continuing)


There is also a small problem linking bin/ps:

cc  -static -o ps devname.o keyword.o nlist.o print.o ps.o -lm -lkvm
s_isnan.o: Definition of symbol _isnan (multiply defined)
isinf.o: Definition of symbol _isnan (multiply defined)
multiply defined: _isnan, type 0x1
multiply defined: _isnan, type 0x1


The above problems occured from a completely clean make.  I also
installed share/mk and include, compiled and installed ld, as, and
gcc, then compiled and installed all libraries (except libg++, since
it failed) before doing anything else.
