Hi Michael,

I make a patch that move gcore.o to makefile.in.
It will make record save build OK in cygwin.

And cygwin "gcore" will get:
>> (gdb) start
>> Temporary breakpoint 1 at 0x4010b0: file
>> /cygdrive/c/study/gcc/gdb/rec/1.c, line 20.
>> Starting program: /home/hzhu/gdb/bgdbcygwin/gdb/a.exe
>> [New Thread 3820.0x600]
>> [New Thread 3820.0x14c]
>> [New Thread 3820.0xf94]
>>
>> Temporary breakpoint 1, main () at /cygdrive/c/study/gcc/gdb/rec/1.c:20
>> 20             int     b = 0;
>> (gdb) gcore
>> Can't create a corefile
>> (gdb)

Please help me review it.

Thanks,
Hui
