Bug with _Complex_I on Solaris 10 and Open Solaris.

Bug with _Complex_I on Solaris 10 and Open Solaris.

[Dr. David Kirkby]

See the code below. It compiles fine on Linux, and also with the Sun compiler on 
both Open Solaris (x86) and Solaris 10 (SPARC).

However, it fails with every gcc version I've tried, and every Solaris system (3 
tested).

This is what I expect, which is what I get on Linux

I've submitted bug reports for Solaris 10 (SPARC)

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42753

and Open Solaris (x86)

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42755

Can anyone suggest a workaround?

Dave
