[tex-k] Running (g)make check on FreeBSD: lib/t1lib, utils/tpic2pdftex

    or maybe it is Linux-specific
    not to require libm for sqrt, floor, and similar math functions

Right.

    unconditionally adding '-lm', except that I seem to remember that some
    systems neither need nor have that library.

Really?  As far as I know everything has -lm.  Before Linux libc "fixed"
this non-problem, it was nearly required to link against it for any
nontrivial program.
