There was some discussion of Solaris builds just yesterday, see the
archives at http://sources.redhat.com/ml/ecos-discuss/

    Mike> Any suggestions are welcome!

The message indicates that you do not have a working gcc installation.
At this stage in the configure script it will generate the following
file conftest.c:

  #line 1044 "configure"
  #include "confdefs.h"

  main(){return(0);}

where confdefs.h is probably an empty file, and try to compile and run
it using something like:

  gcc -o conftest conftest.c
  conftest

Somewhere along the way this fails, so as far as the configure script
is concerned you do not have a working gcc installation. Something
like the 2.95.2 release should be fine, see http://gcc.gnu.org/ for
details.
