Subject: Sparse fixes for http-fetch
X-Git-Tag: v0.99.9~115
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=f5dce80611ed865d2d5d1e76c2c3ae64bf99fe99;p=git.git

Sparse fixes for http-fetch

This patch cleans out all sparse warnings from http-fetch.c

I'm a bit uncomfortable with adding extra #ifdefs to avoid either
'mixing declaration with code' or 'unused variable' warnings, but I
figured that since those functions are already littered with #ifdefs I
might just get away with it. Comments?

[jc: I adjusted Peter's patch to address uncomfortableness issues.]
