Hi,

Since a while, some build systems show lots of warnings like "warning:
ignoring return value of 'fwrite', declared with attribute warn_unused_result"
when building tools/. This isn't seen very often because the tools
aren't rebuilt every time.

It's possible to suppress the warning with -U_FORTIFY_SOURCE. Should we?
