I've decided not to attempt support for Cygwin in the next version of Boost.Filesystem.
I have posted your comments on the cygwin mailing list and post the answer below.
Ha! You must have more charm that I do; there was no reply when I asked a similar question on both that and the cygwin apps list. Good work!
It says that cygwin is not using the GNU C library but newlib which does not have the full set of wide character functions. Any idea how to help newlib get the missing functions?
Cygwin is using the wide char functions provided by newlib. Newlib (http://sources.redhat.com/newlib/) is still lacking a couple of wide char functions so far, namely:
fwprintf fwscanf swprintf swscanf vfwprintf vswprintf vwprintf wprintf wscanf wcstod wcstof wcstold wcsftime wcstok
wcstok has been contributed but isn't checked in so far. As for all the other functions, contributions to newlib are always welcome on the newlib mailing list.
The list of functions and what mailing list to work with are exactly what I wanted to find out. That list of functions just isn't that scary, particularly since the narrow version of the same set of functions would be available to use as a guideline. I'll post something on the newlib list to try to get a bit of direction from them, but my current plan is to twist people's arms to get that set of functions contributed to newlib, and on into cygwin. --Beman
