Yes. You then need to run Sun's make (i.e. /usr/ccs/bin/make). This will
read the Makefile and use your SUNWspro C compiler to build GNU make.

i.e. you need to:

    1. Add /usr/ccs/bin to your path. This is shell-specific. If you
       are using bash, you could do:

           export PATH=$PATH:/usr/ccs/bin

    2. Configure GNU make. It sounds like you've already done this.

    3. Invoke SUN make in the same directory as the makefile. Simply
       type:

           make

       and it should compile GNU make for you.

    4. Install GNU make.

           make install

       You may have to 'su root' for this step, depending on the
       value of '--prefix' you set on the configure step. Beware that
       your PATH environment won't carry over to root. It'd be
       simplest just to give full path to the sun make, i.e.
       from the directory with the Makefile:

           su root
           /usr/ccs/bin/make install

It was my hunch a while ago that Sun make was breaking your GCC build
with a VPATH bug so I suggested that you try using GNU make instead.

Once you've installed GNU make, you should try building GCC again. If
you didn't give configure GNU make with a program prefix then it will
also be called 'make'; ensure you're using the correct one by trying:

    make --version

Sun make won't like this:

    make: Warning: Ignoring DistributedMake -v option
    make: Warning: Ignoring DistributedMake -o option
    make: Fatal error: No dmake output dir argument after -o flag

but GNU make will display its version information:

    GNU Make version 3.79.1, by Richard Stallman and Roland McGrath.

If you still get Sun make then check your PATH for the directory you
installed GNU make in (possibly /usr/local/bin).

Good luck,
