Zaptel on NetBSd

I was compiled zaptel drivers on NetBSD 4.0.1 and have got warnings, listen below…

/usr/src/sys/dev/zaptel/wcfxo/wcfxo.c:116: warning: initialization discards qualifiers from pointer target type /usr/src/sys/dev/zaptel/wcfxo/wcfxo.c:119: warning: initialization discards qualifiers from pointer target type /usr/src/sys/dev/zaptel/wcfxo/wcfxo.c:122: warning: initialization discards qualifiers from pointer target type
I try to fix it, but anyway don’t been successful.

115:/* descriptions for the boards which might match */ 116:static struct wcfxo_desc wcx100p = { "Wildcard X100P", 117://const struct wcfxo_desc wcx100p = { "Wildcard X100P", 118: FLAG_INVERTSER | FLAG_USE_XTAL | FLAG_DOUBLE_CLOCK }; 119:static const struct wcfxo_desc wcx101p = { "Wildcard X101P", 120://const struct wcfxo_desc wcx101p = { "Wildcard X101P", 121: FLAG_USE_XTAL | FLAG_DOUBLE_CLOCK }; 122:static const struct wcfxo_desc generic = { "Generic X100P Clone", 123://const struct wcfxo_desc generic = { "Generic X100P Clone", 124: FLAG_USE_XTAL | FLAG_DOUBLE_CLOCK };
The structure to use with it the next definition.

struct wcfxo_desc { const char *name; unsigned long flags; };
I want give any successful to work fix it. And I hope what anybody can help me.
