It looks like this is still in plan but is it currently possible to specify
environment variables to used in the make command. Our current makefiles
havily use defined environment variables, however when I try to run this
with CDT the variables are not calculated. For instance if I set up an
external program, point it to echo and provide %SBD% as an argument (a
pre-defined variable) the program will return %SBD% not the required value
of that variable.
This is on win2000, sp3 with F1 of cdt installed, and now working thankfully
Cheers In advance

Yes, that's correct. Echo prints the text without substitution (%BOB% for
instance) if it does not recognize this format. I tried yesterday night the
same example on cygwin Win2000 computer and everything worked well. As far
as in your case for any macro format echo never substitutes macros, it seems
to me that it would also fail to substitute %PATH% or $(PATH) or $PATH as
well. Looks like it doesn't understand any macro substitution format. Could
you please try to use absolute path for echo command in your make file?
Could you please also try it for PATH ? In Windows echo is an embedded
command and I guess overrule the path call order.

I think "which" just searches executable with this name in the path order.
If command shell then runs embedded version, you don't know about that.
So please try full path name to call cygwin echo command.
