o Major bugfixes:
- Provide correct replacements for the timeradd() and timersub() functions
for platforms that lack them (for example, windows). The timersub()
function is used when expiring circuits, timeradd() is currently unused.
Patch written by Vektor, who also reported the bug. Thanks! Bugfix
on 0.2.2.24-alpha/0.2.3.1-alpha, fixes bug 4778.
