Subject: Porting to SunOS 5.8:
X-Git-Tag: release-1.0pre3~9
X-Git-Url: https://git.tinc-vpn.org/git/browse?a=commitdiff_plain;h=f8f1007bf469d44480d95d0d78ddc156d00e059f;p=tinc

Porting to SunOS 5.8:
- More #includes Linux doesn't seem to need
- Don't do unsetenv() on SunOS
- Use a replacement asprintf() in case the OS doesn't support it
It now compiles properly under SunOS.
