Subject: sh: sdcc miscompiles (foo = bar)->x = 1 so avoid
X-Git-Url: https://git.ndcode.org/public/gitweb.cgi?a=commitdiff_plain;h=31fca4508cc3414188f91856fb9a703d223db4bc;p=FUZIX.git

sh: sdcc miscompiles (foo = bar)->x = 1 so avoid

It's a strange syntax anyway !

With this applied internal commands sort of work but executing external
commands fails and "set" likewise shows there is some kind of variable space
corruption problem to pin down first
