Hi,
I yesterday reported off-list to Ken that while trying to build
TenFourFox on Intel, I get these warnings (and the compilation
failure).
Compilation uses gcc 4.8 which is "proven" since the beninning.
host_pathsub.o

nsinstall_real

the real failure is perhaps different, since nsinstall fails.
However, today I was upgrading 10.5 macports and cmake compiles with
gcc 6 by default and I noticed this:
/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_devel_cmake/cmake/work/cmake-3.15.4/Source/cmFileCommand.cxx:

while the failure is clearly the std::lround float vs. double issue (I
thought this had been solved?) the warnings below are quite familiar.
Something to worry about? an issue in our chain?
