This patch changes the system mk scripts to enable compilation of programs using the BSD make system to compile with the new libc. In details, it does the following: - it always defines the __MINIX make variable. This can be used, in porting applications, to specialize Makefiles for Minix. - If the environment variable NBSD is set to something different than 'no' and if the compiler is not ack, set NBSD_LIBC to 'yes'. This will set the destination lib directory to '/usr/netbsd/lib' and set up CPPFLAGS and LDFLAGS to use new libc's includes and library directory.
