I'll fix this problem when I'm back to Linux, but the easier* way to fix it
is to add:

flags gcc .AR : [ GLOB $(PATH) $(GCC_BIN_DIRECTORY) : ar ar.exe ] ;
.AR ?= ar ;

And replace the archive action with:

$(.AR) ru...

* Easier, as in more portable, no configuration by the user, no added
documentation on my part ;-) etc.

For this you're going to have to show me how this is happening to you.
mingw-tools.jam uses it's own has its own archive, link, cc, and c++
actions. How can it be using the cygwin libraries? Could you show the output
of the commands called (-n option)?
