I am using the following:
using gcc : cygwin_3.4.4 : /usr/bin/g++ : <compileflags>-DBOOST_POSIX_API <compileflags>-DBOOST_POSIX_PATH ;
using gcc : cygwin_4.3.2 : /usr/bin/g++-4 : <compileflags>-DBOOST_POSIX_API <compileflags>-DBOOST_POSIX_PATH ;

and I try to run the regression tests regularly (bronf1 on trunk). However, I do not know if it is of any help.
