Comment (by stephen):

 It still fails with the "complex_bsd.h" no rule message.

 I looked at Jeremy's patch, and it seemed to me that it did create
 math_bsd.h and complex_bsd.h.  For example, it has lines like this:

 {{{
 --- cephes-2.8/patches/complex_bsd.h.orig       2010-07-26
 08:25:54.654310990 +1000
 +++ cephes-2.8/patches/complex_bsd.h    2010-07-26 08:25:54.658310309
 +1000
 }}}

 This is a diff against a non-existent file, using the "-N" option to diff.
 The patch program creates a new file.

 Makefile then copies this from cephes-2.8/patches to where-ever it is
 needed.  I would probably change the patch so that it is created directly
 in the directory where it is needed.
