CSextractDbl function missing?

[crispinatime]

Hi,

In CS_egm96.c there is a function called

int CSmkBinaryEgm96 (struct cs_Egm96_ *This)

that contains a call to "CSextractDbl" - which is declared in cs_Map.h as

int EXP_LVL5 CSextractDbl (csFILE *aStrm,double* result);

but is not defined - is there a cs_map.c file missing?

Many thanks!
