I was the one you started the thread which ended with the very useful
write-var-to-file. This function works well for me under Windows 2000
with the cygwin version of make. I never tried it with the Windows
native version.

What is the exact problem?

I also run into this problem and I solved it like this (excerpt from my
Makefile to compile a Java project):

# Java source files. The files are found with help of the VPATH feature.
This
# is necessary for the dependency rule '$(CLASS_DIR)/%.class : %.java'.
VPATH = java
JSRCS := $(shell cd java && find ch -name '*.java')

# Define where classes are written to
JOBJS = $(JSRCS:%.java=$(CLASS_DIR)/%.class)
    
# Real location (without VPATH)
REAL_SRCS := $(JSRCS:%.java=java/%.java)

# Compile all Java files in one go
$(CLASS_DIR)/%.class : %.java
    @mkdir -p $(CLASS_DIR)
    $(call write-var-to-file,$(JSRCS_LIST),REAL_SRCS,200)
ifneq ($(findstring jikes,$(JC)),)
# Jikes needs all files on a separate line
    sed 's, ,\n,g' $(JSRCS_LIST) > $(JSRCS_LIST).temp
    mv $(JSRCS_LIST).temp $(JSRCS_LIST)
endif
    $(JC) $(JC_FLAGS) @$(JSRCS_LIST)

HTH,
