It's slightly confusing to have different names for this file on different systems. configure.cache has the disadvantage of having each configure parameter on a new line, which makes it hard to copy and paste them to the command line the next time you run configure; whereas config.status is a shell script (despite not being named like one). On Windows it could have an additional .bat or .cmd extension in order to be a script which can be run again to reconfigure, or it could at least have all the configure parameters on one line for convenience, and be named the same.
