this probably shouldn't be the showstopper as it's not in the official<br>
set of binaries, but just to let you know that the original asymptote<br>
2.28 (as fetched from sourceforge) apparently fails to compile with<br>
XCode 5.1. This is the error:<br>

Apparently a valid workaround seems to be<br>
export CFLAGS="-stdlib=libstdc++"<br>
(I don't know why CFLAGS and not CXXFLAGS – maybe it was a typo), but<br>
that's not the proper way to deal with the issue. The binaries should<br>
depend on libc++, not on libstdc++ to avoid crashes.<br>
<br>
Sadly I'm not able to test anything as my OS is too old. Maybe Dick<br>
can help with this one. I find it weird though that he didn't stumble<br>
upon this issue already.<br>
<br>
<br>
And this is one of the many warnings (the same one as thrown by<br>
Solaris, see below):<br>

The macro GNUC_PREREQ(4,3) simply doesn't do. Probably there should be<br>
a ./configure-time test to check for features like this one.<br>

PS: In contrast to POSIX 2008, both issues here are really "please ask<br>
your software provider to adapt the code" rather than "please ask your<br>
OS provider to fix the issues" ;) ;) ;) ;)<br>
