First do AC_LANG_CPLUSPLUS (or the equivalent) to switch to compiling in
C++).

Then you can simply do :

AC_CHECK_LIB(cgi, main)

(yes, using "main" works - it's a special value in this context).

I don't know if an unmangled name would work now - if it doesn't and you
really do need to check for a particular symbol, you can use
AC_TRY_COMPILE to build your own test.

There's probably other ways, but this is the sort of thing I do.
