RH 8.0 on Dell Lattitude C640. 
Kernel 2.4.20
>Description:
A compile error results when gcc have been configured with:

../gcc-3.2.1/configure --prefix=/static --enable-languages=c --enable-threads=posix --disable-nls --disable-shared --target=i486-pc-linux-gnu

uname -m reports i686 on my system. The last few lines of the compile output have been attached.
>How-To-Repeat:
Configure with the options shown and do:

echo "#define HAVE_GAS_HIDDEN 1" > gcc/autohost.h && \
make -j 1 BOOT_LDFLAGS=-static bootstrap

in your gcc-build directory.
>Fix:
None known.

State-Changed-Why:
    I reopen this report because of this mail from the original reporter
    that didn't make it to the audit trail:
    
    | Oops, sorry - my mistake. I actually did ">>" not ">". I have attached
    | the full compilation output as well as the relevant snippet of my
    | gcc-building script.
    
    I'm still not sure if this is supposed to work though. I'll add the rest
    of the mail including a full build log as an attachment. I also replaced
    the ">" with a ">>" in the How-To-Repeat Section.

State-Changed-Why:
    I don't think this is supposed to work. When doing
    echo "#define HAVE_GAS_HIDDEN 1" >gcc/auto-host.h you just erased the
    rest of auto-host.h. You can't expect the compiler to bootstrap after
    editing random generated config files by hand.
