To be honest, it didn't seem quite right to me either, but I
figured that was down to me not knowing the ins and outs of
how Cygwin handles text modes.
The original logic was:
#if defined(WIN32) || (defined(UNIX) && (O_BINARY != 0))
pushSTACK(S(Kdos)); /* :line-terminator */
pushSTACK(S(Kunix)); /* :line-terminator */
which translates to "if O_BINARY is something other than 0,
then this unix must differentiate between text and binary
streams, so assume that text streams use dos EOLs". That
makes sense, except that O_BINARY is nonzero even on (for
instance) my Cygwin installation, where I selected unix EOLs
as the default with setup.exe.
The patch changes the condition to:
#if defined(WIN32) || (defined(UNIX) && (O_BINARY == 0))
which, as Sam pointed out, would make most unixes (on which
O_BINARY is 0) use dos EOLs.
I tought the UNIX O_BINARY logic was only for CYGWIN and wondered what
other UNIX that could be.
Ok, so we'll have to use
#if defined(WIN32) || \
(defined(UNIX) && (O_BINARY != 0) && !defined(__CYGWIN__))
or make the call slower by doing a dynamic textmount check.
But I really don't want to do that.
