Answering 2 in 1.

I agree that even on Linux this is usually the case, but not
with lndir. 3.2.3 and 3.3.1 produced smaller binaries, while
3.2-3 doubled the size on Cygwin.

Yes, and I also used strip on Cygwin to see it -Wl,-s was
really working. The Makefile is like:

CC      = gcc
CFLAGS  = -O2 -pipe -Wall
LDFLAGS = -Wl,-s
INCLUDE = -I.

all: lndir

lndir:
        $(CC) $(CFLAGS) $(INCLUDE) -o lndir $(LDFLAGS) lndir.c


I just did

$ make
$ make LDFLAGS=
$ make CFLAGS='-Os -pipe -Wall'
$ make CFLAGS='-Os -pipe -Wall' LDFLAGS=
$ make CC=gcc-2

and so on. Anyway, I'll later compile other things to see it
the size changes that much. I was just impressed by the
difference since 3.2-3 on Cygwin is supposed to work like 3.x
on Linux, or not ?
