is this a feature or a bug?

[James Sarrett]

Hi all,

I was trying to write a very simple Makefile this morning, and was 
stymied!  What I thought I meant was this:

xrcs := *.xrc
py_xrcs := $(xrcs:.xrc=_xrc.py)

%_xrc.py: %.xrc
    pywxrc -pv $<

all: $(py_xrcs)

I have 2 .xrc files which need to be turned into _xrc.py files via 
pywxrc.  I'm using GNU make 3.81 on Ubuntu 10.10 (maverick meerkat).  
What appears to actually happen is that the variable py_xrcs ends up 
with only the first filename returned by *.xrc translated to 
file1_xrc.py.  I have found the workaround to be defining xrcs like this:

xrcs := $(wildcard *.xrc)

This seems like it should not be required.  Is this a bug in patsubst?

Thanks very much,
