I'm afraid this is not good enough.  The presence of an unquoted
[ABCDE..._] will cause the shell to look for files named /^#/s/\(
followed by two capital letters or underscores, and then
*\)/_GLIBCPP_\1/g.  Of course, nobody would have a file named like
that, but why take the risk?  Please enclose $a in double quotes.
Similarly for the other occurrences of it.

Thanks for taking care of the problem!
