Symbian uses two version of the GCC compiler (cross-compilers for ARM)
but I did not find the docs.

In any case, to protect the check, you should test the flags for
applicability:

In configure.ac:
XORG_TESTSET_CFLAG([COMPAT_CFLAGS], [-Wc++-compat], [-Werror])

The flags will be added to the variable if they are supported. We never
know for sure with which compiler our code gets built with. I think this
is more than reasonable. Others will step-up to handle the few remainder
cases if any
