I meant GH is an MS Windows app.

All fine now, ggc/doc/ifn.texi was manually patched. Active ports are:

gcc10-bootstrap                @10.5.0_0 
gmp                            @6.3.0_0 
isl                            @0.24_1 
libmpc                         @1.4.1_0 
mpfr                           @4.2.2_0 

The executables in gcc10-bootstrap have the usual names without any additional
add-ons. Configuration was:

env
PKG_CONFIG_PATH=/usr/lib/pkgconfig:/usr/X11/lib/pkgconfig:/usr/X11/share/pkgconfig
PATH=/opt/local/libexec/gcc10-bootstrap/bin:/bin:/usr/bin:/sbin:/usr/sbin:/opt/X11/bin:/opt/local/libexec/perl5.38:/usr/X11/bin:/opt/local/bin:/opt/local/sbin

--with-gxx-libcxx-include-dir="/opt/local/libexec/gcc16/libc++/include/c++/v1"
--with-pkgversion="MacOS PowerPC gcc16 16.1.0_0+stdlib_flag"

config.log records:

The following languages will be built: c,c++,lto,objc,obj-c++
*** This configuration is not supported in the following subdirectories:
     zlib target-libsanitizer target-libvtv target-libphobos target-libgcobol
target-libgo gnattools gotools libgrust target-libada target-libga68
target-zlib target-libbacktrace target-libgfortran target-libffi target-libgm2
target-libgrust target-libgomp
    (Any other directories should still work fine.)

but no version gcc used yet. host-powerpc-apple-darwin9/gcc/config.log records:
/usr/bin/ld64 - GNU ld and gcc (GCC) 10.5.0.

So, after breakfast the build will also have its first break… or faster?
