Question : How to fix assignment of 'ptr to const' to 'ptr' compile error?

typedef struct
{
    SRV_Ntrfc_t          const  *ntrfc;
} SRV_Cnfg_t;


MGR_MR_E   srv_main(  MGR_MC_E    cmd,
                                       MGR_Work_t  *cmw,
                                       MGR_Cnfg_t  *cmc,
                                       MGR_Srv_t   *srv ) {

    Work_t   *wp     = srv->work;
    SRV_Cnfg_t   *cp     = srv->cnfg;
    SRV_Ntrfc_t  *ntrfc  = cp->ntrfc
   ....

Above code was compiled with WindRiver diab 4.2b 'C' compiler without errors.  Compiling this program with WindRiver diab 5.8.0.0 'C' compiler produces the following error:

trying to assign 'ptr to const' to 'ptr'

How to fix this error without changing software functionality?  Maybe some kind of typecast may do it.

You can use const_cast<type>(), e.g.

ntrfc = const_cast<SRV_Ntrfc_t *>(cp->ntrfc);
