The GNU Compile Farm has a wide variety of systems on which you can test bootstrap. I tested the branch on AIX and it broke because the new files are violating a GCC coding style convention: the libgfortran.h header file MUST be the first header file included. Some of the new files in the libgfortran/nca subdirectory include system header files first. This is verboten. It also is incorrect to include libgfortran.h in the source code, and again include it in the coarrays header files. And some system header files are included in source code and some in the coarrays header files. The header file inclusion style should be consistent. But, most importantly, libgfortran.h MUST be included first in any coarrays source code file. Thanks, David
