Re: [Bug-gsl] finite deprecated in OSX, iOS

FYI, autoconf is not supplied by Xcode 5 (or 4.5); it has to be installed, such 
as I have done with MacPorts:

$ xcrun --find autoconf
/opt/local/bin/autoconf

$autoconf --version
autoconf (GNU Autoconf) 2.69

I tried this:

$ autoconf -W all
configure.ac:95: warning: The macro `AC_PROG_LIBTOOL' is obsolete.
configure.ac:95: You should run autoupdate.
aclocal.m4:129: AC_PROG_LIBTOOL is expanded from...
configure.ac:95: the top level
configure.ac:107: warning: The macro `AC_CHECK_LIBM' is obsolete.
configure.ac:107: You should run autoupdate.
aclocal.m4:3593: AC_CHECK_LIBM is expanded from...
configure.ac:107: the top level

I did as I was told:

$ autoupdate
$ autoconf -W all

I then reran configure, and the error from __arm__ being undefined is gone, but 
the Syntax error problem is still there.

I had previously established that running ./configure with no options 
succeeded; I ran it again having defined CC and CPP to clang:

This works. So maybe it’s not clang per se, but something it’s being fed. All 
very confusing. Still waiting for insight.
