2013-08-07Revert previous change to tools/Makefile.gnuhost. When getenv("M4")apb
contains multiple words, flex fails. Adjust tools/autoconf/Makefile to pass the necessary extra arguments via M4=... in CONFIGURE_ENV. This is similar to what used to be in revision 1.4 of tools/autoconf/Makefile, but it's now after instead of before the inclusion of Makefile.gnuhost, because it has to override the value of M4=... that Makefile.gnuhost stores in CONFIGURE_ENV.
2013-08-06Add the "-g -D__gnu__" flags when invoking M4 via CONFIGURE_ARGSapb
in tools/Makefile.gnuhost. This makes the tools version of m4 behave like GNU m4. Remove similar code from tools/autoconf/Makefile, where it didn't work because Makefile.gnuhost would previously have overridden it. This fixes a problem in which the tools version of autoconf complained "M4sugar requires GNU M4. Install it before installing M4sugar or set the M4 environment variable to its path name."
2002-12-08Centralize the definition of the tool name prefix (i.e. "nb") intothorpej
bsd.own.mk, as the _TOOL_PREFIX variable.
