Subject: [boost] [filesystem][cygwin] Standard conformance for wide characters

I've decided not to attempt support for Cygwin in the next version of

Cygwin's lack of library support for wchar_t is the problem . For the
current Boost.Filesystem version (v2), the necessary workarounds are so
pervasive that the implementation code is much harder to read and
maintain. Witness the number of bug reports that are Cygwin specific.
For v3, currently under development, trying to support Cygwin would be
even harder, and would cause a serious delay in development. Plus I'm
tired of waiting for the cygwin folks to come into full C++ conformance.

IIUC, the reason Cygwin doesn't provide C++ standard library support for
wchar_t is that the underlying C library is missing the C wchar_t
functions. Perhaps Boosters who care about Cygwin could spearhead an
effort to add the missing C support? The needed functionality isn't all
that complex; the main problem might be just learning enough about how
Cygwin/GCC is configured and built to be able to add a fairy small
number of C functions.
