Takashi Yano cdf5db22f1 Cygwin: pty: Introduce disable_pcon in environment CYGWIN.
- For programs which does not work properly with pseudo console,
  disable_pcon in environment CYGWIN is introduced. If disable_pcon
  is set, pseudo console support is disabled.

Adding default winvar 'PATH=C:\cygwin64\binZ' to an environment that is
already allocated for 'SYSTEMROOT=ZWINDIR=Z', we need to count that
trailing (Z)ero as well.  Otherwise we trigger this assertion failure:

$ /bin/env -i SYSTEMROOT= WINDIR= /bin/env
assertion "(s - envblock) <= tl" failed: file "/home/corinna/src/cygwin/cygwin-3.0.7/cygwin-3.0.7-1.x86_64/src/newlib-cygwin/winsup/cygwin/environ.cc", line 1302, function: char** build_env(const char* const*, WCHAR*&, int&, bool, HANDLE)

Ken Brown 3a049236db Cygwin: Remove workaround in environ.cc
Commit ebd645e on 2001-10-03 made environ.cc:_addenv() add unneeded
space at the end of the environment block to "work around problems
with some buggy applications."  This clutters the code and is
presumably no longer needed.

Erik M. Bray 7fd70a9706 Move the core environment parsing of environ_init into a new win32env_to_cygenv function.
win32env_to_cygwenv handles converting wchar to char and some other
minor taks.  Optionally it handles converting any paths in variables to
posix paths.

This will be useful for implementing /proc/<pid>/environ

Convert sys_privs to const struct with TOKEN_PRIVILEGES layout.

Dropping max_sys_priv from wincaps requires to make sure that the
bitfield is 8 byte aligned on x86_64, otherwise gcc (5.3 only?)
apparently breaks access to the bitfield (off by 4 bytes).

Johannes Schindelin e0d4e3fec7 Do not treat the command line or environment like paths
* 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.
