* dcrt0.cc (dll_crt0_1), environ.cc (environ_init, getwinenveq,
build_env), strfuncs.cc (sys_wcstombs, sys_wcstombs_alloc),
wchar.c (sys_wcstombs, sys_wcstombs_alloc): avoid mis-conversions
of text that does not, actually, refer to a path or file name
Detailed explanation:
Our WCS -> UTF conversion handles the private Unicode page specially
to allow for otherwise invalid file names. However, this handling makes
no sense for command-lines, nor environment variables, which we would
rather convert verbatim.
As a stop-gap solution, let's just introduce a version of the
sys_wcstombs() function that specifically excludes that file name
conversion magic.
The proper solution is to change sys_wcstombs() to assume that it is not
a path that wants to be converted, and introduce sys_wcstombs_path()
that does, but that is a bigger task which we leave for another patch.
