Subject: Re: misc/455: ports/x11/iv wont compile

 * this will allow it to compile.  whether it is correct or not.......

Thanks, I tested it, it works exactly like you claim (well our ld
doesn't get a signal :), so I committed it, because it seems to reduce 
the brokenness of the port by a significant margin.

 * There is still a problem in src/bin/ibuild with ld getting a sig11
 * (see separate pr) also in src/bin/idraw getting alot of undefined
 * symbols, I haven't figured it out yet....

I spent the better part of the night trying to figure out the
undefined symbol problem.  It is because the library (libIV.a in
src/lib/IV/FREEBSD) is defining a symbol (for instance) as

  _RasterRect__9ivPainterP8ivCanvasiiP8ivRaster

while the source for idraw is referring to it as

  _ivRasterRect__9ivPainterP8ivCanvasiiP8ivRaster

Note the missing "iv".  There is a definition

  #define _lib_iv(name) iv##name

in src/include/InterViews/iv.h, which is used as

  #define RasterRect _lib_iv(RasterRect)

in Unidraw/_defines.h, and this file is included as

  #include <Unidraw/_defines.h>

in Unidraw/enter-scope.h.

My head is spinning fast enough.  Someone please unentangle this.
