System: Linux DervishD 2.4.18 #1 Thu Jul 25 16:31:49 CEST 2002 i686 unknown

host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../gcc-3.2/configure --prefix=/usr --disable-nls --with-cpp-install-dir=lib --enable-languages=c --disable-multilib
>Description:
    When installing, make aborts because I don't have 'tar' on my system and
it insists on installing header files using tar instead of cp. I don't have
a tar on my system because I follow SuSv3 and POSIX and have 'pax' instead.

>How-To-Repeat:
    Just build normally but without a 'tar' binary on the system
    
>Fix:
    Adding 'pax' support (and detection...), adding 'tar' detection and, if
not found, default to 'cp' or just default to 'cp' (the best, IMHO) in file
gcc/config.gcc, variable 'install_headers_dir'. Or better, am I missing a
way of modifying this variable in the build process (the submake on gcc dir
doesn't allow me to override the variable in the Makefile proper)?

    Thanks a lot :)
