[m-users.] Can't compile sample program

[Volker Wysk]

Hello!

I've successfully built and installed the posix library. But the example 
program "hello" can't be built:

In extras/posix:

> mmc  --make libposix
Making libposix.a
Making libposix.so

> sudo checkinstall mmc --make --no-libgrade \
>   libposix.install \
>   --libgrade asm_fast.gc.prof \
>   --libgrade asm_fast.par.gc.stseg \
>   --libgrade asm_fast.gc \
>   --libgrade hlc.gc \
>   --libgrade asm_fast.gc.decldebug.stseg \
>   --libgrade hlc.par.gc \
>   --libgrade asm_fast.gc.debug.stseg \
>   --libgrade asm_fast.gc.trseg.debug.stseg \
>   --libgrade asm_fast.gc.profdeep.stseg \
>   --libgrade asm_fast.gc.memprof \
>   --libgrade asm_fast.gc.trseg \
>   --libgrade hlc.gc.trseg

(This succeeds and installs all grades except for "java".)

> LANG=C mmc --make hello
Making hello

Any hints about what I should try? (I've already read the user manual chapter 
about libraries).
