   The change you require would actually entail more than changing
forward slashes would it not? Absolute paths would need to be changed to
something like /cygdrive/c/xxx/yyy/zzz with possibly some more escapes
being added for spaces, special characters, etc.

   Anyone got some working code implementing this transformation?

   Also, how should Boost Build/Jam know whether to apply the
transformation to a specific path?

   This can not be specified simply for 'all paths in an action' as
Boost Jam has now way of telling what part of an action is a 'path'.

   We already have a :W variable modifier in Boost Jam which does this
conversion for a specific variable content but this works only for a
cygwin built Boost Jam as it uses cygwin's
cygwin_conv_to_posix_path()/cygwin_conv_to_win32_path() APIs.

   I guess one alternative would be to add a new variable modifier to
Boost Jam which would always convert a path from Win32 format to Cygwin
without relying on Cygwin's APIs. And if we could do that then would
there be any point in keeping the old :W modifier around? Or should
perhaps that one be changed to work without cygwin as well?

   Another alternative is to have a rule (whether written using Jam or
as a builtin rule - does not really matter) which implements this
transformation and then call that when needed. Although I do not think
we could use that for transforming paths passed as parameters to actions
so I guess that does not help us much.

   Hmmm, now that I think of it I remember seeing something like this in
the python.jam module... but do not have the time to check right now...

   Anyone else got any more thoughts on this?

   Best regards,
