Other bugs with tcc on FreeBSD:
 -  tcc generated executables are missing an
    entry in their ELF program-header table and so do not
    execute directly.  You can work around this by
    using the base system ld for the final link step.
 -  Someone reported that a few of our headers don't
    compile with tcc.  I haven't tracked down whether
    this is on account of an unsupported Gcc'ism in
    the header or whether this is a bug in tcc.
