Remove disclaimer from up-to-date entries (possibly with some minor changes):
- 'How is fork() implemented?'
- 'How do symbolic links work?'
- 'How do I compile a Win32 executable that doesn't use Cygwin?'
- 'How do I make the console window go away?'
- 'Why does make complain about a "missing separator"?'
- 'Why can't we redistribute Microsoft's Win32 headers?'
- 'How can I debug what's going on?'

EXIT_SIGNAL bit and reorganizes exit value for backwards cygwin handling.
(handle_exceptions): Call signal_exit. Set "core dumped" bit.
(sig_handle): Call signal_exit. Set "core dumped" bit appropriately.
(_addenv): Remove check_null_empty_path from here.
(putenv): Call check_nullempty_path.
(setenv): Call check_nullempty_path for name as well here.
Don't report an error if value is empty string.
(environ_init): Revert usage of newp.
Change type to enum. Change storage class to static. Adjust comments.
(read_etc_passwd): Set passwd_state to different values when loaded
from file in contrast to being emulated.
(search_for): Return default passwd entry if passwd is emulated or
it's a request for the current user. Otherwise return NULL.
pseudo randomness.
* fhandler_random.cc: Rearrange. Use pseudo random number generator
as entropy source if system entropy isn't available and if device is
used as /dev/urandom. Allow initializing device by calling write().
to be set when variable blocksize mode is on.
* fhandler_raw.cc: Eliminate `\n' from trace output.

sys_mbstowcs.
* uinfo.cc (internal_getlogin): Replace calls to wcstombs and
mbstowcs by calls to sys_wcstombs and sys_mbstowcs. Replace
usage of constants by meaningful defines. Use result of
GetSystemDirectory for HOMEPATH and HOMEDRIVE as a last resort.
* syscalls.cc (chroot): Set new root for process.
* path.cc (getcwd_inner): Add parameter to force use of
new root from chroot() call.

chroot() took place.
for second argument.
* path.h: Generalize SYMLINK_* constants to PC_*.
(path_conv): Create a new method. Fold third argument into second.

struct.

* syscalls.cc (_rename): Use already-determined file attributes rather than
