1) if you copy the 10.5sdk from developer-old into the new developer folder sdk folder, the standard ghc distro will work again<div>2) theres a ghc ticket for that, its apparently partly because theres no -nowarnunwind flag or the like<br>

I run haskell on Mac OS X (Snow Leopard). After upgrading my Xcode installation to 4.0 I had a tricky time getting ghc working again; the version bundled with the Haskell Platform no longer works and I had to compile a recent snapshot (ghc-7.1.20110315) from source. This worked fine, but now when I compile my code I keep getting really weird warnings. For instance:<br>
<br>
ld: warning: could not create compact unwind for .LFB3: non-standard register 5 being saved in prolog<br>
<br>
and<br>
<br>
SpecConstr<br>
Function `$w$j{v s3hL} [lid]'<br>
has one call pattern, but the limit is 0<br>
Use -fspec-constr-count=n to set the bound<br>
Use -dppr-debug to see specialisations<br>

Function `$w$j{v s3ic} [lid]'<br>
has two call patterns, but the limit is 1<br>
Use -fspec-constr-count=n to set the bound<br>

The code seems to work, but this is quite irritating. Is there anything that can be done about these warnings?<br>
<br>
Thanks,<br>
