[Bug plugins/46042] New: install-plugin rule exceeds argument line length on a host with argument list limitations


http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46042

           Summary: install-plugin rule exceeds argument line length on a
                    host with argument list limitations
           Product: gcc
           Version: 4.5.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: plugins
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: gary@intrepid.com

patch: work-around command line limit for install-plugin rule

'make install' failed on an old SGI/IRIX/MIPS box.  The install-plugin rule
tried to create a shell variable from the value of the $(PLUGIN_HEADERS) make
variable, and this produced a command line that was too much for the OS to
handle.

The attached patch, diff'ed against the 4.5 branch, implements a work-around. 
Tested both on the SGI/IRIX box, and x86_64 Linux.

This issue is present in the main line/trunk as well.
