The latest build of Yasm, yasm-r1712 is patched and works fine with  
ghc.  For the record, here is the download link:
http://cvs.tortall.net/projects/yasm/snapshots/r1712/  (use yasm- 
r1712-dos ; yasm-r1712 crashes--looking into it.)

As part of testing Yasm, I looked at the next step for the Windows  
native port: building and testing GHC using Yasm as the assembler,  
which may benefit from changing the option flags in compiler/main/ 
DriverPipeline.hs and compiler/main/DynFlags.hs .  I would like to  
change the flags to:
(1) move the hard-coded option parameters for 'runPhase As ...' in  
DriverPipeline.hs into separate option sets in DynFlags.hs --that way  
you only have to look in one place to change the hard-coded options  
(or, in this case, to code them conditionally under a preprocessor  
define USE_YASM);
(2) include parameters for Yasm ("-ax86", "-pgas", "-fwin32"); and,
(3) include Yasm as a configuration option (--enable-yasm).
An alternative implementation would be to add a special command line  
option, --yasm, to enable use of yasm, although this would require  
Makefile changes both for building and testing, in the same way as  
using --pgma, --opta ... to use Yasm as is.  What do you think?

Cheers,
Pete
