Agreed.

Just not as funny as the current approach. This "compile at library build 
time using HOST_CC" must *really* die, IMO.

For some strange reason, I managed to get libtool to use the right CC, 
but that didn't help, as gcc sent incorrect flags to as. Still don't know 
why this happens.

For now, I've compiled and installed impgen manually, and hacked 
libtool.m4 to just run it. Works great.

Somehow, I can't see why having:

    extract_expsyms_cmds='test -f $output_objdir/impgen.c || \
      sed -e "/^# \/\* impgen\.c starts here \*\//,/^# \/\* impgen.c ends 
here \*\// { s/^# //;s/^# *$//; p; }" -e d < $''0 > 
$output_objdir/impgen.c~
      test -f $output_objdir/impgen.exe || (cd $output_objdir && \
      if test "x$HOST_CC" != "x" ; then $HOST_CC -o impgen impgen.c ; \
      else $CC -o impgen impgen.c ; fi)~
      $output_objdir/impgen $dir/$soroot > $output_objdir/$soname-def'


(sorry 'bout the wrapping...) in libtool.m4, when you could build impgen 
during the installation, and then use something like:

    extract_expsyms_cmds='impgen $dir/$soroot >$output_objdir/$soname-def'


Right, it's not a great idea to fix something the wrong way - but then 
again, we're talking about something that's *really* broken, inconcistent 
(any one else cares about HOST_CC...?), and a major PITA for a great 
number of users. (I might be the first, but even the established 
workarounds failed on my setup...)

And now I'm not even sure if anyone knows what the correct solution would 
be... What now?
