I think making debug builds debuggable for people with non-broken
compilers is more important than making debug builds build for people
with broken compilers.

(Under some unstated but I think reasonable, and rebuttable,
assumptions about the sizes of the two sets of people.)

Non-debug builds are, after all, not affected by any of this.
