I ran into a similar problem a long time ago, and I think you're right, the struct2string functions are screwed up. I wrote my own, but now I can't find them. They simply convert the 4 byte integers to 4 chars and build the string from them. Whoever wrote the ones in the header made a big mess of them.

This should be the correct struct2str function (as given in the comment section of codebase.mql4.com/6122) :
Inserted Code
string struct2str(int struct[], int field){
string r="";
int l=field>>16;
if (l==0) return(r);
field&=0xFFFF;
int p=field>>2;
int o=field%4;
for (l=l; l>0; l--){
int x=struct>>(o<<3);
r=r+CharToStr(x&0xFF);
if (o==3) {
o=0;
p++;
x=struct;
} else
o++;
}
return(r);
}
