[Swarm-Support] Pls bring me up to speed on gcc-4.7 and Swarm. Anybody?

[Paul Johnson]

On Fedora 17, we are provided with gcc-4.7.0.  I *thought* everything Swarm was 
fine because I built and RPM and
installed it without any apparent trouble.

However, when I try to compile an application like heatbugs, I see some errors 
that I can't recall seeing before. They
are pasted in below.

What's up with all that disappointment?

Worst fear: "retval_t" and "FILE" been moved from the deprecated category to 
the completely gone category of gcc?

In a Debian system, where I still have gcc-4.6, I can find retval_t here:

$ pwd
/usr/lib/gcc/x86_64-linux-gnu/4.6.3
address@hidden:4.6.3$ grep -r retval_t *
include/objc/deprecated/Object.h:- (retval_t)forward:(SEL)aSel 
:(arglist_t)argFrame;
include/objc/deprecated/Object.h:- (retval_t)performv:(SEL)aSel 
:(arglist_t)argFrame;
include/objc/deprecated/objc_msg_sendv.h:typedef void* retval_t;               
/* return value */
include/objc/deprecated/objc_msg_sendv.h:objc_EXPORT retval_t 
objc_msg_sendv(id, SEL, arglist_t);

But on Fedora 17, I don't find anything while grepping for retval_t.

Anyway, I'm *hopping* I just build Swarm incorrectly--but fear your advice will 
be different.

Further, I have no explanation why Swarm itself would seem to build when system 
doesn't have retval_t or FILE types.
Weird, right?

Here's that disappointing make output from heatbugs:

-Wno-protocol -Wno-long-long -fPIC -D_GNU_SOURCE
