broken line continuation in DOS files

[Eric Blake]

I checked out the jikes compiler via CVS
(:pserver:address@hidden:/usr/cvs/jikes, password anoncvs,
module jikes).  I'm using cygwin 1.3.2 on a Win98, with the drive
mounted in textmode, along with the latest cygwin release of automake,
unmodified:

$ automake --version
automake (GNU automake) 1.5
Written by Tom Tromey <address@hidden>.
[...]


The Makefile.am that comes with jikes has entries such as:

jikes_SOURCES = \
ast.cpp \
body.cpp \
...

Since my drive is mounted textmode, the cvs checkout puts \\\r\n
sequences in Makefile.am.  However, automake reads the file in binary
mode, so it only recognizes \\\n as line-continuations.  As a result,
the generated Makefile.in ends up looking like:

jikes_SOURCES = \

...
.PHONY: all ...

ast.cpp \

body.cpp \
...


And this causes make to issue the famous "*** missing separator.  Stop."
error after configuration, since the makefile ends in a list of
filenames that do not form a rule.


I'm not sure where to make the patch, but it should be a simple matter
of telling automake to open Makefile.am in text mode, rather than binary
mode, or else treating \\\r, \\\r\n, and \\\n as equivalent line
continuations.  I was able to work around the bug locally by stripping
out all \r from Makefile.am.
