[M3devel] subrange or enum, with cvshead

[Tony Hosking]

I tracked this one down to a problem with building m3cc on x86_64.   
It turns out (for reasons yet to be determined) that floating point  
constants get built wrong when m3cc is configured with CC="gcc -m32"  
that the problem goes away.  This problem is internal to the gcc- 
based backend, so dtoa is not involved.
