Hi,

adding isl as a dependency to gcc6-aux could be done. However, adding
it still does not explain why GCC was getting configured to use it. If
GCC does not see isl in the tree and it is not explicitly configured
with isl, it should not use it...
But I am glad that you could get gcc6-aux installed.

Regarding gcc10-aux, that error is not related to the Ada backend, but
with libgcc. What operating system are you using? What architecture?
Could you try to compile lang/gcc10 and see if you get the same error?
gcc10-aux is based on lang/gcc10. Since I have not touched gcc10
outside of the Ada parts, you should get the same error chain. If that
is not the case, you may have found something that I will need to fix
(probably something related to the compiler not being the system
default but gcc6-aux). Or maybe there is an issue with lang/gcc10 that
has gone undetected and therefore has been included into gcc10-aux.

Regards,
Fer
