mergemem, is it really needed

Hi,

Upon reading the mergemem thread, some vague memory
from my read-everything days came floating up...
And a 'info gcc' gave me:

`-fshared-data'
Requests that the data and non-`const' variables of this
compilation be shared data rather than private data. The
distinction makes sense only on certain operating systems, where
shared data is shared between processes running the same program,
while private data exists in one copy per process.

Wouldn't this give the same functionality as mergemem,
at a cheaper cost???

Rik.
