NetBSD-(majorversion). Using a fixed value causes C++ bina- |

For instance, if the source directory is /usr/src, a setting of |
|
``-M /usr/obj'' will place build-time files under |
|
/usr/obj/usr/src/bin, /usr/obj/usr/src/lib, |
|
/usr/obj/usr/src/usr.bin, and so forth. |
|
|
|
If a relative path is specified, it will be converted to an |

absolute path before being used. build.sh imposes the restric- |
|
tion that the argument to the -M option must not begin with a |
|
``$'' (dollar sign) character; otherwise it would be too diffi- |
|
cult to determine whether the value is an absolute or a rela- |

|
|
|
In normal use, exactly one of the -M or -O options should be |
|
specified. If neither -M nor -O is specified, then a default |
|
object directory will be chosen according to rules in |
|
<bsd.obj.mk>. Relying on this default is not recommended |
|
because it is determined by complex rules that are influenced |
|
by the values of several variables and by the location of the |
