I was digging through the glibc make file to see how to rebuild just the
crtx files and I ran across a make construct I did not understand on the
following line
make subdir=csu -C csu ..=../ others
It's building the target others after changing to the subdirectory csu
and setting the value of the variable subdir to "csu",
but what does the "..=../" do?
I have been unable to find any reference to a special variable ".."
Is is some sort of path manipulation? Any pointers would be appreciated.
