[ruby-core:64418] [ruby-trunk - Bug #10145] win32/configure.bat should have CRLF eol-style.

Issue #10145 has been updated by Masamitsu Murase.


I'm sorry for confusing you.

I mean that r47015 should be reverted.
(r47017 reverted r47016, not r47015.)

r47015 changed eol-style to LF from CRLF.
This change should be reverted so that cmd.exe can parse configure.bat correctly.

Bug #10145: win32/configure.bat should have CRLF eol-style.

----------------------------------------
win32/configure.bat does not parse command line arguments correctly with revision 47015 and later.

For example, "win32\configure.bat --disable-install-doc --prefix=D:\test" outputs invalid "prefix" definition in Makefile.

It seems that this issue is caused by strange behavior of cmd.exe for Bat file, which includes LF eol.
i.e. This issue does not occur with revision 46795 and older.

How to reproduce this issue:

1 Run the following command on command prompt in the root directory of ruby source.

~~~
win32\configure.bat --disable-install-doc --prefix=D:\test
~~~

2 Then, Makefile contains invalid variable definitions.
  "prefix" and "EXTOUT" are invalid.

~~~
### Makefile for ruby  ###
MAKE = nmake
srcdir = .
prefix = /usr
EXTSTATIC = 
RDOCTARGET = nodoc
EXTOUT = D:\test
...
~~~

  The expected output is the following:

~~~
### Makefile for ruby  ###
MAKE = nmake
srcdir = .
prefix = D:/test
EXTSTATIC = 
RDOCTARGET = nodoc
...
~~~

I have not investigated the detail of this strange behavior of cmd.exe, but I think that cmd.exe does not expect LF eol-style.
If there is no specific reason, configure.bat should have CRLF eol instead.

Regards,
Murase
