Comment (by Gilles Mouchard):

 Below a patch I apply to boost 1_60_0 to make it compile with mingw (both
 mingw32 and mingw-w64). It is derived from fedora patches. The patch
 forces compiling for NT and adds extra assembly directive for gas.
 The only stuff that doesn't seem to work is exception handling: a throw in
 a coroutine, for example, invariably results in a call to terminate().
