Re: friends.cpp won't compile on FreeBSD

[Ari Johnson]

Alright, I removed my local copy of the cvs and checked it out anew, and
now everything worked fine (except piostreams, but that's probably because
I'm missing some library or something, and I don't use them anyhow, so I'm
not overly concerned).  Now, on to using gcc 3.x.  The compilation fails
when it gets to slog.cpp, which gets a ton of errors from
/usr/local/lib/gcc-lib/i386-portbld-freebsd4.7/3.3/include/g++-v3/cmath,
which is included eventually by fstream, which slog.h includes.  The
errors are all like this:
/usr/local/lib/gcc-lib/i386-portbld-freebsd4.7/3.3/include/g++-v3/cmath:
In function `float std::tanh(float)':
/usr/local/lib/gcc-lib/i386-portbld-freebsd4.7/3.3/include/g++-v3/cmath:489:
error: `::
   tanhf' undeclared (first use here)

This doesn't happen when I compile anything else that includes fstream, so
I'm thinking it's a problem with the order in which slog.cpp includes
files.  I'm running FreeBSD-STABLE, which is basically 4.7, and the
gcc-3.3 port, version string is 'gcc version 3.3 20021014 (experimental)
[FreeBSD]', with no further modifications.  I've also tried the gcc ports
for versions 3.0, 3.1, and 3.2, and all result in the same problem.  I
just can't comprehend the sheer weirdness of this error.
