[M3devel] missing M3_FRONT_FLAGS from libm3: m3overrides

[Peter Eiserloh]

Hi Guys,

I downloaded a new archive: cm3-src-all-d5.8.0-2009-05-15-06-57-11.tgz,
as I wanted to look at Olaf's changes.

I attempted to "./scripts/do-cm3-std.sh build", and while
it did build m3core, it failed to build libm3.

Its 'm3overrides' file attempts to append ( using += ) to a
variable (M3_FRONT_FLAGS), but since the variable doesn't
exist it fails.  Should an obliq script fail like that, if
you attempt to append to a non-existing variable, or should
it silently create that variable?

Log follows:
