Re: .ctor section of shared libraries with PathScale compiler

[Ralf Wildenhues]

Thanks Noah.  I installed that, but changed the constant to be a #define
in the header file.

To ease Jeff's concerns about -shared: if libtool supports shared
libraries for the system/compiler in question, then they will be
preferred over static libs.  So -shared is not needed in order for the
test to be effective.  And we don't want it to fail in the static-only
case.

Cheers,
Ralf
