I try in cygwin with:
configure --disable-sid --disable-rda --disable-binutils --disable-gas
--disable-ld --disable-gprof --enable-targets=all --enable-64-bits-bfd
CFLAGS=-g
configure --disable-sid --disable-rda --disable-binutils --disable-gas
--disable-ld --disable-gprof
Build is OK.

I think in gcore.o, there is not some host-special code. Just some target hook.
I suggest mv gcore.o to makefile.in and add code to check return value
in record.o when call gcore function.
What do you think about it?
