with the introduction of the conditional
.if ! empty(_HOST_CYGWIN)
to bsd.sys.mk, make in src/tools fails with the error
nbmake: "/home/src/share/mk/bsd.sys.mk" line 71: Malformed conditional (! empty(_HOST_CYGWIN))
apparently this is because _HOST_CYGWIN does not exist. perhaps there is
change to one of the other share/mk templates that defines _HOST_CYGWIN
that has not appeared on the public cvs repository. adding _HOST_CYGWIN=
just before the conditional causes make to behave as expected.
however, i do not believe this should fail, ie: for a non-existent variable
it ought to evaluate to true.
build.sh's building of the host tools was the first to reveal this to me.
