Ugh, I'm mazed again.

cygwin-1.1.4:

1) Consider qqq goes to a directory that is mounted without the -b option (CYGWIN=binmode).

If I issue

sh.exe -c "tar -O -xf file.tar > qqq"

qqq contains CRCRLF.

If I issue

cmd.exe /c "tar -O -xf file.tar > qqq"

qqq contains CRLF.

Why does output differ?


2) Why hinfo::init_std_file_from_handle doesn't use __fmode anymore?


3) What is the precedence of CYGWIN=binmode, Program Options, mounting
directories with the -b option, linking with binmode.o/textmode.o, explicit
opening a file in binary/text mode? And how does it affect regular
files and stdin/stdout?
