According to Andrew's reply on gdb@ I created a new file i386-cygwin-tdep.c and added everything needed to get it working. Ok to commit? Corinna 2003-03-20 Corinna Vinschen * Makefile.in (ALLDEPFILES): Add i386-cygwin-tdep.c. (i386-cygwin-tdep.o): Add dependencies. * defs.h (enum gdb_osabi): Add GDB_OSABI_CYGWIN. * i386-cygwin-tdep.c: New file. * osabi.c (gdb_osabi_name): Add string for GDB_OSABI_CYGWIN. * config/i386/cygwin.mt (TDEPFILES): Add i386-cygwin-tdep.o.
