Aside from any othe consideration, you should ALWAYS catch a function
pointer like this in a variable and make sure it's not NULL. Either GetEntry
isn't finding your function (maybe try "_testproc"), or there is some bug in
DLX.

> - and a second problem: "extended DLX" does not support C++:
It probably does, but doesn't now it yet. The problem is most likely that
the linker script it probably comes with doesn't yet mention
the sections introduced by gcc 2.95. Something similar to this is required:
----
OUTPUT_FORMAT("coff-go32")
FORCE_COMMON_ALLOCATION
SECTIONS {
  .dlxdata : {
    *(.text)
    *(.gnu.linkonce.t*)
    *(.const*)
    *(.ro*)
    *(.gnu.linkonce.r*)
    etext  =  . ; _etext = .;
    dlx_first_ctor = . ;
    *(.ctor)
    dlx_last_ctor = . ;
    dlx_first_dtor = . ;
    *(.dtor)
    dlx_last_dtor = . ;
    *(.data)
    *(.gnu.linkonce.d*)
    ___EH_FRAME_BEGIN__ = . ;
    *(.eh_fram*)
    ___EH_FRAME_END__ = . ;
    LONG(0)
    *(.gcc_exc*)
    edata  =  . ; _edata = .;
    _object.2 = . ;
    . += 24 ;
    *(.bss)
    *(COMMON)
    end = . ; _end = .;
  }
}

This is taken from my own patched DLX library, which includes exception
support and compression.
