Uppercase and lowercase for same word mixed together

[jinCN]

you store vars in a style VARNAME_$(d),don't you think there will be something wrong when in a situation uppercase and lowercase for same word are mixed together?

I'm not sure what you mean - could you give an example?

Variables in make are case sensitive. More over there is nearly no chance that anybody will define variable with name of the sort SRCS_/home/user/some/directory (that is a full name of variable). If anybody makes a mistake and instead of SRCS in his Rules.mk defines Srcs or srcs then he should correct it - there is no provision to guess that, and there will not be since that can break some make files where e.g. some user uses srcs for his internal purposes.

What I mean is not someone stupidly using a wrong case variable name (SRCS to be sRcs),but is generating a wrong case variable TARGETS_/home/user/Some/Directory,this generated name can be correctly used at one place,but other one use TARGETS_/home/user/some/directory to point to it but get nothing.It's just similar to the trap that TARGETS_/home/user/some/AWAY/../directory is not equal to TARGETS_/home/user/some/directory

Can you give a specific example of a Rules.mk file that would result in $(d) expanding with the wrong case in two different places?
