--- Comment #195 from Iain Sandoe <iains at gcc dot gnu.org> --- (In reply to Peter Dyballa from comment #194) > Gcc10-bootstrap has no dependencies. That should mean that its build started > with Apple's GCC-4.2. Sergey can exactly tell. Makes sense (the bootstrap really does need to try and avoid deps). IDK what GCC-10 version was built for that bootstrap. FTR: I built : https://github.com/iains/gcc-10-branch/tree/gcc-10-5Dr0-pre-0 which is the most up-to-date version of gcc-10.5 - but is still buildable with a C++98 compiler (i.e. Apple gcc-4.2)
