Error report

[Atom]

I think i found some error in the source!   In the crypto\asn1\a_strnid.c file there is the following function:   int ASN1_STRING_set_default_mask_asc(char *p) {  unsigned long mask;  char *end;  if(!strncmp(p, "MASK:", 5)) {   if(!p[5]) return 0;   mask = strtoul(p + 5, &end, 0);   if(*end) return 0;  } else if(!strcmp(p, "nombstr"))     mask = ~(B_ASN1_BMPSTRING|B_ASN1_UTF8STRING);  else if(!strcmp(p, "pkix"))    mask = ~B_ASN1_T61STRING;  else if(!strcmp(p, "utf8only")) mask = B_ASN1_UTF8STRING;  else if(!strcmp(p, "default"))      mask = 0xFFFFFFFFL;  else return 0;  ASN1_STRING_set_default_mask(mask);  return 1; }   I tried to compile by MS-VC it but I got error in the following lines:   mask = ~(B_ASN1_BMPSTRING|B_ASN1_UTF8STRING); mask = ~B_ASN1_T61STRING;   The error message was the following:   conversion from 'const int ' to 'unsigned long ', signed/unsigned mismatch     Is a good solution to typecast to unsigned int? Is there someone who maintains the code?   Thanks a lot!
