dnl Add the -lm library if math functions cannot be used without it.
dnl This check is important on cygwin because of the bizarre way that they
dnl have organized functions into libraries. On cygwin, both libc.a and
dnl libm.a are symbolic links to a single lib libcygwin.a. This means that
dnl 1) linking with -lm is not necessary, and
dnl 2) linking with -lm is dangerous if the order of libraries is wrong
dnl In particular, if you compile any program with -mno-cygwin and link with
dnl -lm, it will crash instantly when it is run. This happens because the
dnl linker incorrectly links the Cygwin libm.a (==libcygwin.a), which replaces
dnl the ___main function instead of allowing it to be defined by
dnl /usr/lib/mingw/libmingw32.a as it should be.
dnl
dnl On MacOS X, this test will find that -lm is unnecessary and leave it out.
dnl
dnl Just check a few math functions. If they are all found without
dnl -lm, then we must not need -lm.
