Quoth Dmitry Goncharov:
Humm, in the following example do you want N and M to expand to different values? If yes, can you please tell us about your use case where such behavior is needed?.POSIX: M=word N=${M:word=a\ b} all:; echo ${N} ${M:word=a\ b}
I would think they should expand to different values. I don’t have much of a use case, I was just playing around with the beginnings of a make implementation and wondering how it should be; noticed how weirdly gmake and bmake behave. Perhaps I should have just posted to the Austin list?
If we can agree, then i'll file a request to opengroup to explicitly state that this "When an escaped <newline> is found in a command line in a makefile, the command line shall contain the <backslash>, the <newline>, and the next line, except that the first character of the next line shall not be included if it is a <tab>". takes place after variable expansion.
As I stand here, utterly without use case, just standard lawyering, I’m not sure what agreement I could try to pursue. A resolution would be welcome though; please do.
