OK, I added the complex.h header as described there to
scipy/linalg/src/fblaswrap_veclib_c.c and was able to get scipy
compiled. I read a few of the links in the page you cited, and the
only thing I could find about the brokenness of complex in veclib was:

Are any 10.3 platforms 64 bit? If not, there may be little danger in
simply adding it, or conditionally adding it for non-64 bit platforms.
The other question is: what has recently changed vis-a-vis veclib that
is now causing the compile on 10.3 to break. I compiled scipy from
svn several months ago, though I don't have the revision number off
the top of head.
I had 9 errors on my test, but all were related to loadmat. My guess
is this is that endianess is not being handled properly in the test.
Everything else appears to pass.
I'm attaching a patch against r3435 if you decide this should be added.
