Newbie query: where'd the '!' come from?

Apologies in advance for what is obviously a dfu question but I'm trying to
get jam to work and it's driving me nuts. System is Win2K. I was able to
build the regex libs using nmake on the vc6.mak file so the install isn't
totally frelled.

It seems to be working until I get this "...skipped" (see snippet below)
because of a path that contains '!' characters. I grep'd everything I
could think of for "libs!thread!" and came up empty. Can someone tell me
where that path is being assembled?

<snippet>
...failed msvc-C++-action
libs\thread\build\bin\libboost_thread\msvc\debug\runti
me-link-dynamic\threading-multi\exceptions.obj ...
...skipped
<libs!thread!build\libboost_thread\msvc\debug\runtime-link-dynamic\th

Thanks for any help.
