Indeed 'GDC' is it. See my <https://inbox.sourceware.org/gcc-patches/87mtlk8m1m....@euler.schwinge.homeip.net> for example: > [...] I built myself a stock GCC 9.1 with '--enable-languages=d', and via > '[...]/configure [...] CC=gcc-4.8 CXX=g++-4.8 GDC=[GCC 9.1]/bin/gdc [...]' > I'm able to successfully bootstrap GCC, including GCC/D, in a mixed > GCC 4.8/9.1 configuration, with subsequent good-looking 'make check-d' > results.

[...] Re GCC 9.1, however beware of <https://gcc.gnu.org/PR104749> "stage1 d21 fails to link with GDC 9.1".
