I know, I wasn't complaining about the submission format, just covering 
my back in case I said something stupid.  The lookover was intended to 
speed up the process by getting trivial problems out of the way early on.

Running autoreconf in the libgfortran directory did the trick. 
Unfortunately, I'm seeing testsuite failures in the C interop testcases. 
   The following error is given in all the cases I looked at:
In file included from /usr/include/math.h:28,
                  from 
/Users/tobi/src/pristine/gcc/testsuite/gfortran.dg/bind_c_dts_driver.c:1:
/usr/include/architecture/i386/math.h: In function '__inline_signbitf':
/usr/include/architecture/i386/math.h:192: error: initializer element is 
not computable at load time
/usr/include/architecture/i386/math.h: In function '__inline_signbitd':
/usr/include/architecture/i386/math.h:193: error: initializer element is 
not computable at load time
/usr/include/architecture/i386/math.h: In function '__inline_signbit':
/usr/include/architecture/i386/math.h:194: error: initializer element is 
not computable at load time

I'll try fixing this later tonight by following the testsuite manual's 
recommendation of not including system headers, but instead writing the 
required prototypes explicitly.

I couldn't see a ChangeLog on the fortran-experiments branch, where's it?
