           Summary: i386-elf build references nonexistent crt0.o, libsim.a
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Keywords: build
          Severity: normal
          Priority: P2
         Component: bootstrap
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: dhazeghi at yahoo dot com
                CC: gcc-bugs at gcc dot gnu dot org

With current mainline (combined tree), building cross to i386-elf fails, when configuring 
libstdc++-v3. The C compiler check fails:

checking for i386-elf-gcc... (cached)  /home/dara/mainline/objdir/gcc/xgcc -B/home/dara/
mainline/objdir/gcc/ -nostdinc -B/home/dara/mainline/objdir/i386-elf/newlib/ -isystem /home/
dara/mainline/objdir/i386-elf/newlib/targ-include -isystem /home/dara/mainline/combined/
newlib/libc/include -B/usr/local/i386-elf/bin/ -B/usr/local/i386-elf/lib/ -isystem /usr/local/
i386-elf/include -isystem /usr/local/i386-elf/sys-include -L/home/dara/mainline/objdir/ld
checking for C compiler default output... configure: error: C compiler cannot create executables
See `config.log' for more details.
make: *** [configure-target-libstdc++-v3] Error 1

The part that is failing is:

configure:2352:  /home/dara/mainline/objdir/gcc/xgcc -B/home/dara/mainline/objdir/gcc/ -
nostdinc -B/home/dara/mainline/objdir/i386-elf/newlib/ -isystem /home/dara/mainline/objdir/
i386-elf/newlib/targ-include -isystem /home/dara/mainline/combined/newlib/libc/include -B/
usr/local/i386-elf/bin/ -B/usr/local/i386-elf/lib/ -isystem /usr/local/i386-elf/include -isystem /
usr/local/i386-elf/sys-include -L/home/dara/mainline/objdir/ld -O2 -g -O2 -O2 -g -O2  
conftest.c  >&5
/home/dara/mainline/objdir/gcc/collect-ld: cannot open crt0.o: No such file or directory
collect2: ld returned 1 exit status

However, this can't be worked around like PR12019, because no crt0.o and libsim.a (also needed) 
has been build. What has been build (in libgloss) is cygmon-crt0.o and libcygmon.a. Placing those 
files in the search path and renaming them (to crt0.o and libsim.a) results in:

configure:2352:  /home/dara/mainline/objdir/gcc/xgcc -B/home/dara/mainline/objdir/gcc/ -

It appears as if i386-elf is considered to be equivalent to cygwin by newlib, but not by gcc.
