I'm afraid this doesn't seem to be the case. I investigated a bit and it seems that the wide character support is a newlib issue rather than a cygwin one proper (newlib is to cygwin as glibc is to linux). > > As regards the usable char_traits and friends, if you can provide me > > a test program I can try compiling it using STLport and report back > > the results. > > Try this one.

When using stlport the source doesn't even compile (see attached). I fear this the end of LyX on Cygwin. Now I also have a useless Qt4/Cygwin library :( What really bothers me is that MSVC can do it but not GCC. -- Enrico
