Hi, when fixing transmission to build on Haiku, the GCI student renamed a local atoui() function to avoid a name clash: https://bitbucket.org/haikuports/haikuports/pull-request/89/transmission-282-recipe-and-patch/diff#Lnet-p2p/transmission/patches/transmission-2.82.patchT70 It seems atoui() is nowhere specified, I can't find it on opengroup, nor in Linux, nor even in the ZETA headers I have. It's not used at all in our own code, there is really few chances it could have been used already in external code... I think we should remove it, no need to pollute the global namespace with this.
