$(shell case ...) -- problem with embedded parens

[Yakov Lerner]

How can I insert a 1-line 'case' statement into '$(shell ...) ?
Make is misunderstanding the right paren after 'case X in pattern)'
as end of $(shell ...). How do I do it ?
I cannot find the right way to quote the paren in 'pattern)'

I tried several variants now:

  GCC_VERSION = $(shell g++ -dumpversion )
  LIB5 = $(shell case "$$GCC_VERSION" in 2.9*|3.0*|3.1\) echo 1;; *\) echo 0;; 
esac; )
  #                                                   ^^           ^^
  all:
        echo LIB5=$(LIB5)

and this:
  RP=)
  LIB5 = $(shell case "$$GCC_VERSION" in 2.9*|3.0*|3.1$RP echo 1;; *$RP echo 
0;; esac; )

and this:
  LIB5 = $(shell { case "$$GCC_VERSION" in 2.9*|3.0*|3.1) echo 1;; *) echo 0;; 
esac; } )

It didn't work.

Is this possible?
