Subject: Build fix: stop initialising an auto char array.
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ian/git?a=commitdiff_plain;h=f04923abbcd676585548c5824262cecb47ba6d11;p=sgt-puzzles.git

Build fix: stop initialising an auto char array.

Checking with the standards, I think this is legal C99, but not legal
C89 - and we are compiling in C89 mode. Why _every_ version of gcc
didn't object, given all the warning and pedantry options, I'm not
sure, but one did, so I should fix it.
