Hi,
There's a significant difference between /usr/bin/libtool from
pkg://solaris/developer/build/libtool@2.4.2,5.11-0.175.1.0.0.24.0:20120904T171232Z
and
pkg://solaris/developer/build/libtool@2.4.2,5.12-5.12.0.0.0.5.0:20120924T234901Z
Is this intentional?

I don't remember an intentional change to libtool, but as the s12userland gate buildson shared machines which also build ON, they have gcc-45 installed, andgiven the gccreferences in the diffs here perhaps you've found that affects libtool.so that's something

to note.

does it do bad things? it might be worth filing a bug if so.

TIA
