Bug description: Type of the parameter conflicts with previous declaration of function

When compiling using a C compiler, it does not allow parameters that are defined as const to be passed to a function that does not have the const qualifier in the prototype. Also, there are some parameter mismatches. Details below.

---------- begin [main/network.c] ----------
ERROR :129 Type of the parameter conflicts with previous declaration of function .
INFORMATIONAL :129 Prototype has type pointer to unsigned character .
INFORMATIONAL :129 Argument has type pointer to constant unsigned character .
---------- end [network.qwobj] ----------

Line 129:

host_info = gethostbyname(host);

But host is const char *. So I had to change line to as follows:
host_info = gethostbyname((char *)host);

---------- begin [fsock.qwobj] ----------
ERROR :110 Type of the parameter conflicts with previous declaration of function .
INFORMATIONAL :110 Prototype has type pointer to unsigned character .
INFORMATIONAL :110 Argument has type pointer to constant unsigned character .
ERROR :183 Type of the parameter conflicts with previous declaration of function .
INFORMATIONAL :183 Prototype has type pointer to unsigned character .
INFORMATIONAL :183 Argument has type pointer to signed integer .
ERROR :183 Type of the parameter conflicts with previous declaration of function .
INFORMATIONAL :183 Prototype has type pointer to signed integer .
INFORMATIONAL :183 Argument has type pointer to unsigned integer .
---------- end [fsock.qwobj] ----------

Line 110:

host_info = gethostbyname((char *)addr);
But addr is const char *. So I had to change line to as follows:
host_info = gethostbyname((char *)addr);

Line 183:
Protoype for getsockopt is: getsockopt(int, int, int, char *, int *).

However, Line 183 contains:

if (getsockopt(sockfd, SOL_SOCKET, SO_ERROR, &error, &len) < 0) {

where error is int and len is socklen_t. I had to change line to as follows:

if (getsockopt(sockfd, SOL_SOCKET, SO_ERROR, (char *)&error, (int *)&len) < 0) {

I hope that these types of changes are made, so as to compile easily on any platform.
