Thanks for the bug report.  The patch below should fix that.
I have committed that change, so it will be included in next rotd
release.

Actually Hans Boehm or one of his contributors is responsible for that.
We have just updated the version of the Boehm collector that we include
with the Mercury distribution.  (I have forwarded the patch below to
Hans Boehm for inclusion in the his distribution of the Boehm collector.)

Thanks for the information.

Does `gcc -s' (i.e. `ld -s') work?  I remember from previous versions
of cygwin that the stand-alone `strip' program worked, but running
`ld -s' did not work, at least not when linking the Mercury compiler
itself.  It may work for small programs but not for large ones.

Actually don't worry about going to any effort to answer that one.
Sometime soon, before the next release, I will need to test Mercury
on Windows again, and when I do so I will see whether `gcc -s' works. 
If so, I'll make stripping the default on Windows like it is on our
other platforms.
