[Hope I got the NetBSD list right...]
Hi all,
bmake appears to export ${.MAKE.LEVEL} into the environment, which sh
doesn't support, due to the leading '.'. Normally this is ignored,
but for example Tinderbox cleans the environment by unsetting
everything except a small list of variables, resulting in an error.
pmake (FreeBSD's make) exports it as ${__MKLVL__} (IIRC), which is
more portable.
I've worked around it in Tinderbox by adding .MAKE.LEVEL to the 'safe'
variable list, but I think exporting incompatible envars to sh(1) is
undesirable.
Can anyone come up with a possibly solution? My preferred solution is
to export __MKLVL__ and allow ${.MAKE.LEVEL} to be recognised as
${__MKLVL__} in Makefiles, possibly with a warning?
I'll see if I can make a patch for this behaviour, unless anyone has a
better idea.
Chris
