Share windows_thread_info between gdb and gdbserver This introduces a new file, nat/windows-nat.h, which holds the definition of windows_thread_info. This is now shared between gdb and gdbserver. Note that the two implementations different slightly. gdb had a couple of fields ("name" and "reload_context") that gdbserver did not; while gdbserver had one field ("base_context") that gdb did not, plus better comments. The new file preserves all the fields, and the comments. gdb/ChangeLog 2019-10-29 Tom Tromey * windows-nat.c (struct windows_thread_info): Remove. * nat/windows-nat.h: New file. gdb/gdbserver/ChangeLog 2019-10-29 Tom Tromey * win32-low.h (struct windows_thread_info): Remove.
