winsup/ChangeLog:
* Makefile.common (COMPILE_CXX): Add support for per-file overrides
to exclude $(nostdinc) and $(nostdincxx) from compiler flags.
(COMPILE_CC): Likewise for $(nostdinc).
winsup/cygwin/ChangeLog:
* Makefile.in (DLL_OFILES): Add libstdcxx_wrapper.o
(libstdcxx_wrapper_CFLAGS): Add flags for new module.
(_cygwin_crt0_common_STDINCFLAGS): Define per-file override.
(libstdcxx_wrapper_STDINCFLAGS, cxx_STDINCFLAGS): Likewise.
* cxx.cc: Include "cygwin-cxx.h".
(operator new): Tweak prototype for full standards compliance.
(operator new[]): Likewise.
(operator new (nothrow)): New fallback function.
(operator new[] (nothrow), operator delete (nothrow),
operator delete[] (nothrow)): Likewise.
(default_cygwin_cxx_malloc): New struct of pointers to the above,
for final last-resort fallback default.
* cygwin-cxx.h: New file.
(struct per_process_cxx_malloc): Define.
(default_cygwin_cxx_malloc): Declare extern.
* cygwin.din (__wrap__ZdaPv): Export new wrapper.
(__wrap__ZdaPvRKSt9nothrow_t, __wrap__ZdlPv,
__wrap__ZdlPvRKSt9nothrow_t, __wrap__Znaj,
__wrap__ZnajRKSt9nothrow_t, __wrap__Znwj,
__wrap__ZnwjRKSt9nothrow_t): Likewise.
* globals.cc (__cygwin_user_data): Init newly-repurposed 'forkee'
field (now 'cxx_malloc') to point to default_cygwin_cxx_malloc.
* libstdcxx_wrapper.cc: New file.
(__wrap__ZdaPv, __wrap__ZdaPvRKSt9nothrow_t, __wrap__ZdlPv,
__wrap__ZdlPvRKSt9nothrow_t, __wrap__Znaj,
__wrap__ZnajRKSt9nothrow_t, __wrap__Znwj,
__wrap__ZnwjRKSt9nothrow_t): Define wrapper functions for libstdc++
malloc operators and their overrides.
* winsup.h (default_cygwin_cxx_malloc): Declare extern.
* include/cygwin/version.h (CYGWIN_VERSION_API_MINOR): Bump.
* include/sys/cygwin.h (struct per_process_cxx_malloc): Forward
declare here.
(struct per_process::forkee): Rename and repurpose from this ...
(struct per_process::cxx_malloc): ... to this.
* lib/_cygwin_crt0_common.cc: Include cygwin-cxx.h.
(WEAK): Define shorthand helper macro.
(__cygwin_cxx_malloc): Define and populate with weak references
to whatever libstdc++ malloc operators will be visible at final
link time for Cygwin apps and dlls.
(_cygwin_crt0_common): Always look up cygwin DLL's internal
per_process data, and don't test for (impossible) failure. Inherit
any members of __cygwin_cxx_malloc that we don't have overrides
for from the DLL's default and store the resulting overall set of
overrides back into the DLL's global per_process data.
