BuildWarnings

@@ -1 +1 @@
 Warnings seen during the build don't necessarily warrant tickets of their own, since they aren't breaking the build. However, one of our goals is to have a (nearly) warnings-free build, so if your build has warnings, document them here, and someone may eventually be able to fix them or update {{{config/auto/warnings.pm}}} to stop complaining about them.

+
+nwellnhof: I just fixed a bunch of warnings. This is what I get with Debian unstable, i386, GCC 4.4.5, non-optimized
+
+The following are caused by -Wbad-function-cast and can be avoided by removing the cast. I'm not sure if this is safe for g++.
+
+{{{
+src/hash.c: In function ‘Parrot_hash_thaw’:
+src/hash.c:681: warning: cast from function call of type ‘INTVAL’ to non-matching type ‘enum <anonymous>’
+src/hash.c:682: warning: cast from function call of type ‘INTVAL’ to non-matching type ‘enum <anonymous>’
+src/nci/signatures.c: In function ‘Parrot_nci_sig_to_pcc’:
+src/nci/signatures.c:184: warning: cast from function call of type ‘INTVAL’ to non-matching type ‘enum <anonymous>’
+}}}
+
+Calls to parrot_hash_put with const keys or values:
+
+{{{
+src/runcore/main.c: In function ‘parrot_hash_oplib’:
+src/runcore/main.c:345: warning: cast discards qualifiers from pointer target type
+src/runcore/main.c:348: warning: cast discards qualifiers from pointer target type
+src/runcore/main.c:349: warning: cast discards qualifiers from pointer target type
+}}}
+
+These could be fixed with a temporary variable:
+
+{{{
+./src/pmc/imageiothaw.pmc: In function ‘Parrot_ImageIOThaw_shift_float’:
+./src/pmc/imageiothaw.pmc:240: warning: cast discards qualifiers from pointer target type
+./src/pmc/imageiothaw.pmc: In function ‘Parrot_ImageIOThaw_shift_integer’:
+./src/pmc/imageiothaw.pmc:220: warning: cast discards qualifiers from pointer target type
+./src/pmc/imageiothaw.pmc: In function ‘Parrot_ImageIOThaw_shift_string’:
+./src/pmc/imageiothaw.pmc:276: warning: cast discards qualifiers from pointer target type
+}}}
