1. Some people don't fancy auto-linking.

2. People responding with "+N".. Which of the following would you prefer?
And give rationale for your preference, and optionally give rationales for
not preferring others:

A) Having file names with "32" *and* "64" on them?

B) Having current names indicate 32 and adding "64" to file names otherwise?

C) Having current names indicate the "default" system address-model and add
"32" or "64" to indicate the non-default?

D) Having the current names and placing 32 bit address-model variants in
"stage/lib32" and 64 bit in "stage/lib64"? (Equivalently for install

E) Having the current names and placing 32 bit address-model variants in
"stage/lib" and 64 bit in "stage/lib64"? (Equivalently for install location)

F) Having the current names and placing the "default" system address-model
variants in "stage/lib" and the non-default in "stage/lib32" or
"stage/lib64"? (Equivalently for install location)
