Reproducible: Always

Steps to Reproduce:
1. Compile ActionMonkey code as per http://wiki.mozilla.org/JavaScript:ActionMonkey#How_to_build
Actual Results:  
Part of the compilation messages includes the following:

No warning in current code base. Command to compile editline.c file is
gcc-4.2 -arch x86_64 -o editline.o -c -fvisibility=hidden -DANSI_ARROWS -DHAVE_TCGETATTR -DHIDE -DUSE_DIRENT -DSYS_UNIX -DHAVE_STDLIB -DUNIQUE_HISTORY -DOSTYPE=\"Darwin\" -DOSARCH=Darwin  -I/builds/slave/m-cen-osx64-ntly/build/js/src/editline -I. -I../../../dist/include -I../../../dist/include/nsprpub  -I/builds/slave/m-cen-osx64-ntly/build/obj-firefox/x86_64/dist/include/nspr   -fPIC  -Wall -W -Wno-unused -Wpointer-arith -Wcast-align -W -gdwarf-2 -isysroot /Developer/SDKs/MacOSX10.6.sdk -fno-strict-aliasing -fpascal-strings -fno-common -pthread  -DNDEBUG -DTRIMMED -gdwarf-2 -O3 -fomit-frame-pointer -fno-stack-protector   -include ../js-confdefs.h -DMOZILLA_CLIENT -MD -MF .deps/editline.pp /builds/slave/m-cen-osx64-ntly/build/js/src/editline/editline.c

There is no reference of '-fno-rtti' and I could not find the error in linux and macos nightly builds also and hence closing the bug.
