That will work, but:

        AS
        LD

are not defined in configure, AS is defined as ($CC)

Defining LDFLAGS CFLAGS to "-B/opt/sfw/bin" doesn't help either...
Also, defining/setting GCC_EXEC_PREFIX does not help either...

So, I still need to move ld and as (gld, gas) around...

cfmakeraw is a bsd 4.4 routine, therefore it is not available in any svr4
Unix. Also, configure does not check for the availability of cfmakeraw... ;-(

So, my solution seems to be the most simple, as it repeats the implementation
of cfmakeraw...

You are right! Running the compiled version does not "work", as I always do
get "permission errors"! So, I will start writing Solaris code... ;-)
