Question for Benjamin Herr:

My gdc line numbers appear to be different from yours.
I presume you are referring to this line in lexer.c:

assert(sizeof(long) == 4); // some dependencies

which I "fixed" to:

assert(sizeof(long) >= 4); // some dependencies

Is this correct?

In aggregate.h the "offending line" seems to be:

#define CLASSINFO_SIZE  0x3C            // value of ClassInfo.size

I wasn't sure exactly what to do with this.  Please post your diffs.

Thanks,

 I think that gdc is actually very close to being clean, "fixing" only
 <built-dir>/gcc/d/dmd/lexer.c:1533 and
 <built-dir>/gcc/d/dmd/aggregate.h:197 got it to compile here.
 
 However Phobos seems very "broken".
 Would it not be easier to maintain Phobos if we finally reorganised the
 standard library after all these years, so the things that are vital to
 the language and required to compile simple programs are separated from
 tools and convenience wrappers?
 
 Trying to get a PPC64 build going myself, but I need a fully 64 OS
 first (at the moment I only have 32-bit Mac OS X and 32-bit Linux)


 Gentoo has quite cool 64bit support.

Yes, mine are quite outdated.

I did indeed refer to this line. I do not know whether changing the
assert will eventually destroy the world, though.

 In aggregate.h the "offending line" seems to be:
 
 #define CLASSINFO_SIZE  0x3C            // value of ClassInfo.size

I think my guesswork eventually lead me to use
#define CLASSINFO_SIZE \
  (sizeof(void*)*2 * 4 + sizeof(void*)*5 + sizeof(int)*2)

I hope that my very unscientific hacks are of any use,
