At least SunOS 5.10 has setenv and unsetenv (at least it has manpages

miss them.

I am not sure. You see: I have asked in the german usenet (in dcoup for all who speak german) and been told ny Daniel Rock in a very informative answer that setenv() and unsetenv() were introduced in UNIX 03 (SUSv3). UNIX 98 did not know these functions. Only Solaris 10 was UNIX 03 certified, Solaris 9 and older had been certified UNIX 98 or less. setenv() and unsetenv() had been introduced into Solaris during the development of Solaris 10. [I'd like to add: Solaris 9 is still supported by Sun (till 2nd calendar quarter of 2009).]

On http://www.opengroup.org/openbrand/register/ you could find other systems on which you cannot be sure to find unsetenv().

I'd like to thanks to Daniel Rock for posting the above facts.
