* pathsys.h - PATHNAME struct

/*
* PATHNAME - a name of a file, broken into <grist>dir/base/suffix(member)
*
* <grist> - salt to distinguish between targets that would otherwise have the
* same name - it never appears in the bound name of a target.
*
* (member) - archive member name: the syntax is arbitrary, but must agree in
* path_parse(), path_build() and the Jambase.
