(mainly in fhandler*) start fixing gcc 4.7.2 mismatch between regparm
definitions and declarations.
* gendef: Define some functions to take @ declaration to accommodate _regN
defines which use __stdcall.
* gentls_offsets: Define __regN macros as empty.
* autoload.cc (wsock_init): Remove unneeded regparm attribute.
* winsup.h (__reg1): Define.
(__reg2): Define.
(__reg3): Define.
* advapi32.cc (DuplicateTokenEx): Coerce some initializers to avoid warnings
from gcc 4.7.2.
* exceptions.cc (status_info): Declare struct to use NTSTATUS.
(cygwin_exception::dump_exception): Coerce e->ExceptionCode to NTSTATUS.
* fhandler_clipboard.cc (cygnativeformat): Redefine as UINT to avoid gcc 4.7.2
warnings.
(fhandler_dev_clipboard::read): Ditto.
(export_malloc_called): Delete.
(internal_malloc_determined): New variable.
(malloc_init): Control calculation of internal/external malloc based on
'internal_malloc_determined'. Use import_address() to determine if malloc in
user_data is ours or not.
* miscfuncs.cc (thread_wrapper): Make static.
(__import_address): Define new function.
* miscfuncs.h (import_address): New define.
(__import_address): Declare new function.
instead, thus simplifying code allocating and filling pfri. Drop size
and use constant expression in NtSetInformationFile call. Add comments.
Drop redundant test for fs_serial_number and change comment accordingly.
* syscalls.cc (rename): Check for cross-device situation before
touching anything. Explain why. Workaround NFS bug in call to
NtSetInformationFile(FileRenameInformation).
that we're looking for the current thread.
(pthread_rwlock::tryrdlock): Eliminate self variable. Accommodate change in
lookup_reader().
(pthread_rwlock::unlock): Ditto.
(pthread_rwlock::rdlock): Ditto. Move add_reader call after writer tests to
more closely mimic old behavior.
(pthread_rwlock::wrlock): Accommodate change in lookup_reader().
* thread.h ((pthread_rwlock::lookup_reader): Eliminate argument.
pointer to allocated RWLOCK_READER structure.
(pthread_rwlock::rdlock): Reorganize to reflect new add_reader functionality.
(pthread_rwlock::tryrdlock): Ditto. Remove unneeded call to lookup_reader().
* thread.h (pthread_rwlock::RWLOCK_READER::RWLOCK_READER): New constructor.
(pthread_rwlock::add_reader): Reflect new functionality.
available in a limited fashion when exiting.
(sig_dispatch_pending): Ditto.
(sig_send): Ditto.
(exit_thread): Rearrange to avoid an unnecessary DuplicateProcess when exiting.
(wait_sig): Allow special signals when exiting.
