Which version of Make are you using?

In fact a makefile troubleshooting target was added PRINT.% which prints the
value of a make variable.  eg. PRINT.CPPFLAGS

This shouldn't cause problems as to my knowledge GNU make target names are
always case sensitive.

aware of a solution, but I was wondering if any of the build system expects
might know why “print” on at least 2 of my build systems is now being
treated  differently. Works as expected on linux.
