I'd suggest removing the ">/dev/null 2>&1" suffix from the CC command in the rounding.h section of the Makefile to see what is wrong.  I'd imagine it is some kind of a compiler failure.

I've committed a change to the Makefile.in file to show more info when creating rounding.h fails.  You can see that diff via gitweb:

http://git.samba.org/?p=rsync.git;a=commitdiff;h=ebac03192584817d626574db28b97ef274683aa5

Please let me know what the compiler error is you encountered.

Sorry for not responding.  This is the make output once the redirection to /dev/null is removed:

gmake: *** [rounding.h] Error 1

On my system, I have /usr/local/include/iconv.h (FreeBSD convention for non-BSD code) and I did supply CPPFLAGS="-I/usr/local/include" to configure.  It seems that the bug is that the rule for rounding.h should be more like

  if $(CC) $(CFLAGS) $(CPPFLAGS) $(LDFLAGS)

so that the user-provided CPPFLAGS is respected.

Thanks for figuring out what was wrong.  I've checked-in a fix for this.
