Indeed it is.  I was pleasantly surprised to learn that '-package text' 
was all I needed to use HaXmL.

Unfortunately, that isn't the problem.  I set prefix=c:/... when 
invoking configure, and configure used that path in its output.

But unfortunately the Makefile.inc used to build hmake does some tricky 
$(PWD) shenanigans that have nothing to do with configure, and then 
passes the resulting path to ghc.  Unfortunately, $(PWD) returns 
Cygwin-style paths, and I failed to find a good workaround for this in 
the few minutes I spent looking at it.

Anyway, I'm relieved that HaXmL is in hslibs.
