Subject: tool: move tool_ftruncate64 to tool_util.c
X-Git-Tag: curl-8_8_0~157
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9fc4b2c78c5a2619e1423e56a98b503d363c085f;p=thirdparty%2Fcurl.git

tool: move tool_ftruncate64 to tool_util.c

... and the prototype to tool_setup.h, to make them both available more
widely and accurately.

Follow-up to 00bef95946d3511

Fixes #13458
Closes #13459
