Getting an intermittent failure on Windows where the expscan.h header apparently isn't present on the file system soon enough for the build to succeed (a subsequent reinvocation of the build command does succeed.) Try the standard technique of making another file write depend on the outputs of the header and src file, then define a target depending on that sentinel file and make the obj libraries depend on that target.

|
# PERPLEX_EXECUTABLE - path to the perplex program
