Re: the Right place to change a target default for a common compiler flag?


Iain,

I am currently bootstrapping on i686-apple-darwin9 with the current patch:

I am currently at stage 3 and I see -gstrict-dwarf in the log file.

I don't know if it is the Right place, but it seems to work so far.

Cheers,

Dominique
