Build failure in libgfortran on i386-pc-solaris2.10

Build failure in libgfortran on i386-pc-solaris2.10

[Art Haas]

Hi.

My bootstrap builds have been failing in the 'libgfortran' portion
of the build since this patch:

2009-07-27  Tobias Burnus  <burnus@net-b.de>

        PR fortran/40863
        * c99_functions.c: Define complex I, if not defined.
        Create prototypes for C99 functions to silence warnings.
        * gfortran.map: Add missing functions to GFORTRAN_C99_1.0
        and new GFORTRAN_C99_1.1.

Here's the error message from the build log:

Anyone else building on Solaris 10 seeing this problem?

I've got the same problem on both Solaris 10/x86 and Solaris 11/SPARC (and
most likely, IRIX 6.5 will be affected, too).  I've file PR
libfortran/41169 for the issue, assigned to Tobias.

It seems that the underlying issue is a problem in GCC's complex support on
Solaris 2, though.

I've stopped building the fortran compiler for the moment. I haven't dug
into what preprocessor trickery is needed to get this code to build just
yet. I will keep an eye on the PR and be glad to test any potential
patches offered.
