initialization.
* dcrt0.cc (initial_env): Can it really be true that XP doesn't allow attaching
a debugger during DLL attach?  Add temporary workaround.
(dll_crt0_0): Ensure that _impure_ptr stdio is initialized before any threads.
(dll_crt0_1): Move _impure_ptr initialization to dll_crt0_0.
* exceptions.cc (try_to_debug): Reinstate old method for looping while
debugging.
* syscalls.cc (_cygwin_istext_for_stdio): Regularize debugging output.  Remove
hopefully extraneous check.
(setmode_helper): Add debugging output for improbable case.  Use "binary"
rather "raw" for consistency.
