* include/sys/cygwin.h: Allow definition of per_process even when not compiling with C++. (cygwin_getinfo_types): Add CW_USER_DATA. * lib/_cygwin_crt0_common.cc (_cygwin_crt0_common): Get __cygwin_user_data pointer from cygwin_internal. If it doesn't exist, return failure. Use either this pointer or passed in pointer throughout. Clear forkee. * lib/crt0.h: Accomodate argument changes to _cygwin_crt0_common. * lib/cygwin_attach_dll.c (cygwin_attach_dll): Reorganize to allow use of newer binaries with older DLLs. Detect older DLLs when _cygwin_crt0_common returns 0 and allocate space for a per_process structure on the stack. * lib/cygwin_crt0.c (cygwin_crt0): Ditto.
