This would also not work when cross-compiling, I think, since manpages
would always be regenerated when the binaries are built and the
cross-compiled binaries would not run on the build machine.
We decided we didn't wanted to ship (or require help2man), so when we
converted to non-recursive Makefile, we solved this problem by added
dependency
foo.1: foo$(EXEEXT)
but this dependency is only turned on if foo.1 is not present (at
configure time) or if '.svn' is present. The latter indicating that we
are not building from a tarball. These conditions are checked at
configure time and propagated to the makefile via an AM_CONDITIONAL.
I'm not 100% happy with this solution though because it creates a
different dependency graph for maintainers and users similar to
AM_MAINTAINER_MODE.
Cheers,
Peter
