Hello, 

I was trying to compile project from coin-or (http://www.coin-or.org) using
the cygwin tools and I found a problem: 
.deps/ClpCholeskyBase.Plo:1: *** multiple target patterns. (and several
other error messages from this kind) 

So I searched in google some hints and found that this is a "well know"
problem. It seems that make 3.81 has some difficulties to handle "automatic
header file dependencies". One solution is to use make 3.80. But I don't
understand why this problem is still not corrected ?? 

Your sincerely, 

YC

PS: I added the comment made on the coin-or website related to this problem
with reference to the bug description (see the 2006 year ...). 

* On Cygwin, GNU make version 3.81-1 delivered by the default setup program
doesn't work with the automatic header file dependencies, generated by the
compilers. 

The error message you will see because of this bug will look something like
this: 

make[2]: Entering directory
`/home/andreasw/COIN-svn/OBJgcc-debug/Clp/trunk/Clp/src'
.deps/ClpCholeskyBase.Plo:1: *** multiple target patterns. Stop. 

Here are two suggested fixes: 
1. Try to obtain the previous version (3.80); for example, you can download
it from http://cygwin.paracoda.com/release/make/make-3.80-1.tar.bz2. 
2. Obtain a fixed 3.81 version, for example from
http://www.cmake.org/files/cygwin/make.exe. (See the Cygwin mailing list
postings http://cygwin.com/ml/cygwin/2006-09/msg00315.html and
http://cygwin.com/ml/cygwin/2006-09/msg00153.html)
