First we get a couple of warnings fro some files, but then one file
refuses to compile (see below). I didn't notice any other warnings or
failures during Configure.pl and/or during compilation.

First we get a couple of warnings fro some files, but then one file
refuses to compile (see below). I didn't notice any other warnings or
failures during Configure.pl and/or during compilation.

Thanks for the report.

We should fix a code generator to handle these, but that's a low priority
unless I or someone else has a brilliant idea which makes it take five
minutes.

This code's going away.

I added a couple of D2FPTR macros, as we've borrowed them from Perl 5, in
r34293. Hopefully this will clear up the warnings.

I added some function decorations in r34295 which should clear up these
warnings.

exception,

I manually fixed these in r34094 and fixed our preprocessor to reject all
CONST_STRING macros broken across lines in r34095, so this problem should
never recur.

Thanks for looking into it. I synced to r34297 and it seems to compile
in Tru64, thanks!

I am seeing some new warnings, if I find the time I'll file a new bug on
those. An easy quick one to fix would be this:

cc: Info: ./include/parrot/sub.h, line 47: Trailing comma found in
enumerator list. (trailcomma)
} sub_flags_enum;
^

Trailing commas in enum lists are not portable across cranky C compilers.

Fixed in r34299, thanks. I cranked up the optimization level to -O2 and am
fixing as many warnings as possible with GCC 4.3, but I'm sure that leaves
plenty for pickier compilers to complain about.

Another large batch of errors seemingly came from these in nci.c:

cc: Info: src/nci.c, line 6614: In this statement, "pcf_v_JOS" of type
"pointer
to function (pointer to struct parrot_interp_t, pointer to struct PMC)
returning void", is being converted to "pointer to void". Such a cast
is not permitted by the standard. (nonstandcast)
PMC_data(temp_pmc) = (void *)pcf_v_JOS;
-------------------------------------^

More cowbell, errr, D2FPTR().
