I would create src/lib/libkse/{libpthread,libthread}, and have src/lib/libkse/Makefile.inc0 that contains everything to build the libs except for the -D's and the lib name. Have src/lib/libkse/{libpthread,libthread}/Makefile include ../Makefile.inc0 and define the missing parts. The BSD Makefile framework really does depend and expect separate directories for each product. -- -- David (obrien@FreeBSD.org)
