Description:
1. The bundled readline interrupts configure under cygwin.
2. The default C compiler flag -O3 doesn't work properly under cygwin with gcc 3.4.4
Both of them seems to be platform relevant issues, but a platform specific configure patch is still welcomed.
Some details:
1. Cygwin doesn't provide a sys/ttydefaults.h file, some people say a copy from *nix is fine.
2. -frename-registers option is the bad. So, instead of CFLAGS=-O2, CFLAGS=-fno-rename-registers also make the life better. Since I'm not familiar with gcc stuffs, I can't figure out what happened indeed. Also, gcc4 seems to work well.
$ gcc -v

It works fine.
