[LIP] Who provides strrev?

Hi all,

Following is an interesting thread on PLUG mailing list. I wonder which standard 
provides function strrev. A guy moving from turbo C to linux is complaining..

I searched around and came up with some interesting URLs.

http://www.gnu.org/software/libc/libc.html

GLibc claims it supports ISO and POSIX. Couldn't find anything for those two 
standards and strrev..

Watcom and Visual C++ seems to be bigger provider of that function.. Check

http://www.cygwin.com/ml/cygwin/1997-11/msg00370.html

So far, I haven't seen anything which says strrev is either ISO/POSIX or ANSI. 
Any idea what standard supports it?

For starters, I checked on a linux and a freeBSD system. None of them supports it..
