Subject: portability: warn if provided snprintf.c is used
X-Git-Tag: v0.2.0~74
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?p=secnet.git;a=commitdiff_plain;h=dee2e14c6ebac12102256639fc9e53d21eb871b2;ds=sidebyside

portability: warn if provided snprintf.c is used

We don't have any visibility of changes to fix bugs in the snprintf
which is supplied with secnet.  Therefore at the very least we should
print a warning if we turn out to use it, rather than perhaps silently
using an ancient and perhaps-buggy implementation.
