GDC environment variable

GDC environment variable

[Dave Blanchard]

Is there an environment variable like 'CC' or 'CXX', which specifies the name of the D compiler to use, which I might need to set when bootstrapping GCC? Thanks.

I do see make using ‘GDC' while building gcc compiler, maybe try changing that ?

Indeed 'GDC' is it.  See my
<https://inbox.sourceware.org/gcc-patches/87mtlk8m1m.fsf@euler.schwinge.homeip.net>
for example:

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

I expect it to be `DC`.
