I try to build a 64 bit version of ECL on Windows by specifying in the Makefile

ECL_WIN64 = 1

But the *features* list still contains the symbol :WIN32 ...

Do I misunderstand the meaning of :WIN32?
Is the build version still a 64 bit version and :WIN32 is added by error?
Is the variable ECL_WIN64 just ignored?

Thanks, Dietrich

Here a diff of my Makefile:

git diff
