Proposed fix
PR108612 - m2/gm2-libs-iso/ClientSocket.mod:229:1: error: control
reaches end of non-void function [-Werror=return-type]
PR108551 - gcc/m2/gm2-libs-pim/Termbase.mod:128:1: error: control
reaches end of non-void function [-Werror=return-type]
The immediate fixes would be to ensure that
the offending procedure functions return a value.
However the front end does not correctly declared the throw function to be
noreturn. Also HALT, Halt, Raise procedures in the libraries need
the <* noreturn *> attribute to be applied. Finally when these changes
have been made the bootstrap tools mc and pge need rebuilding.
The patch also changes the build flags for m2 libraries to -Wreturn-type
-fcase.
(It it worth checking whether -fcase needs a 2nd implementation should
-fno-exceptions be used - and call Halt).
