Thank you all for your replies. I tried this:

define genalldocs
xsl/alldocs_$(1).xsl: genalldocs.php $(wildcard $(DOCS)/$(1)/*.xml)
        ${PHP} php/genalldocs.php $(CURDIR)/$(DOCS)/$(1)/ >$@

endef

$(call genalldocs,l)
$(call genalldocs,k)
$(call genalldocs,a)

But when at least one docs/a/*.xml is newer than xsl/alldocs_a.xsl I get this 
error:

*** No rule to make target `docs/a/a182.xml
', needed by `xsl/alldocs_a.xsl'.  Stop.

Notice the crlf. a182.xml is the last a/*.xml file. The same error occurs with 
the k- and l-directory. Every time the last *.xml file is mentioned in the 
error message.

Any idea what causes this error and how to prevent it?

I'm using make 3.80 and WindowsXP.

With kindly regards,

Douwe.
