remake 4.2.1+dbg-1.3 has a problem in that in installs gnumake.h which conflicts with the same header in GNU make. I've just put out 4.2.1+dbg-1.4 to fix this. It also improves the --post-mortem option so that it persists when recursing directories and has an updated manual page documenting the recent option additions.
committed, thanks!
