Compile Warnings?

[Reid]

I’ve just updated from CVS and am now getting some warnings while building LLVM:

Linking z bytecode library
WARNING: Type conflict between types named ‘struct.z_stream_s’.
Src=’ %struct.z_stream_s’.
Dest=’ %struct.z_stream_s’
WARNING: Type conflict between types named ‘struct.internal_state’.
Src=’ %struct.internal_state’.
Dest=’ %struct.internal_state’
WARNING: Type conflict between types named ‘struct.z_stream_s’.
Src=’ %struct.z_stream_s’.
Dest=’ %struct.z_stream_s’
WARNING: Type conflict between types named ‘struct.internal_state’.
Src=’ %struct.internal_state’.
Dest=’ %struct.internal_state’
…

Are these okay? I remember Chris saying that “any warning during compilation was not acceptable” a while back. Just wanted to check with you guys before I ignore these warnings.

These warnings are coming from zlib, which we now include in the runtime
libraries directory. This is a real type-safety problem in libz, which we
should either fix in our imported source or eliminate libz from the
runtime directory.

I'll file a bug, but for now, you can safely ignore the warning.
