[clue-tech] Portability of shell expressions in a Makefile

[Matt Gushee]

Hello, all--

I am using the following to set a variable in a Makefile:

	SOLID=$(shell \
		version=`ocamlc -version`; \
		major=$${version:0:4}; \
		minor=$${version:5}; \
		if [ $$major = "3.08" ] && [ $$minor ] && \
			[ $$minor -ge 3 ]; then \
			echo "-DSOLID_RELIEF"; \
		else \
			echo ""; \
		fi )

This has the desired effect in bash. Can anyone tell me if it will work 
with other Bourne-compatible shells? And while we're at it, how about 
non-GNU make implementations?

Thanks in advance for any info.
