From my experience with the compiler/linkers
on Sun, the only substantiative change is the
use of a thread-aware errno mechanism. If the
program is unthreaded, the errno will work
normally even with -mt specified.
Of course, it is the responsibility of the
caller to protect the library against concurrent
calls via locking, but that and -mt are what
we've used in the past to make non-thread-safe
I'd like to suggest that the configure script
be changed to add -mt to the solaris linker
options for Solaris (only).
ps: would you like this submitted via bugzilla,for your records?
