Basically I have installed the latest Cygwin and:

- There is a missing boost/stacktrace/detail/push_options.pp

- There is a missing boost/stacktrace/detail/pop_options.pp

- I had to change the scope of GetModuleFileNameA in:
stacktrace/detail/location_from_symbol.hpp:
if (!GetModuleFileNameA(handle, file_name_, DEFAULT_PATH_SIZE_))

- I had to change some __POSIX_VISIBLE macros in the system header files 
to enable some functions:
/usr/include/stdio.h:337:#if 1//__POSIX_VISIBLE
/usr/include/sys/signal.h:177:#if 1//__POSIX_VISIBLE
/cygwin64/usr/include/sys/unistd.h:292:#if 1//__BSD_VISIBLE || 
__POSIX_VISIBLE >= 200112 || __XSI_VISIBLE >= 4

Thanks,
