I am having trouble using the library classes SINGLE_MATH and DOUBLE_MATH.

In particular, the problem seems to be that the C maths library is not
automatically linked when these classes (which need it) are used. Even
if I add `-lm' to the EXTERNAL list in the SDF, the compilation system
does not link it last (as is required by the standard Unix linker, ld).

So far, the only workaround I have found is to generate a C-package, and
edit the makefile by hand to put -lm at the end of the link list. This
is a nuisance, and slows development!

Has anybody else out there had this problem? Am I missing something here?

As usual, thanks in advance for any help.
