           Summary: Bad path to the C/C++ frontend causes build problems
           Product: Build scripts
           Version: 1.0
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: P2
         Component: autoconf
        AssignedTo: criswell at uiuc.edu
        ReportedBy: sabre at nondot.org


This is an important usability problem with the current build scripts.  In
particular:

1. When configuring, autoconf should check whether the CFE is found (in the
   specified directory) and works.  If not, print out LOUD warnings, but do
   not set LLVMGCCPATH in the Makefile.config.

2. When building the runtime directory, don't build subdirs if the LLVMGCCPATH
   variable is not set, instead, print out another loud warning.

This is really important because this seems to be, by far, the most serious
end-user problem encountered by people.  Especially since the getting started
guide was broken in the 1.0 release.
