[Mingw-users] Well-optimizing compiler and a weirdness in the mailing list

["Cornelius Riemenschneider" <c.r1@xxxxxx>]

Hi,
1st: In my subscription-confirming mail It was stated i'm IP 
>>We have received a request from 10.3.1.93 for subscription of your
10.x.x.x is the private class A-Network. It may be true for a sf.net-server but i'm definitly not reachable at this IP ;)
2nd: The reason i'm writing this: I thought of gcc as an optimizing compiler. But, the source at the end of the mail compiles to a winapp >800KB. Doing the same with MSVC++ 6 results in a 60KB app. COmpiling options for g++: -O0 -Os -pedantic -w -Wall -c -fmessage-length=0
 the -O0 is caused by eclipse...
ld: -Wl,-O1
as: -O1 (may or may not be wrong...)
options for MSVC++:
/nologo /G6 /Gr /Zp1 /ML /W4 /GX /O1 /Ob2 /D "WIN32" /D "NDEBUG" /D "_CONSOLE" /D "_MBCS" /Fo"Release/" /Fd"Release/" /FD /c 
looks maybe weird as they are build by the IDE...

Attention: this is a hack, copying some files from a samba share. Not all code is by me but from public domain. All important strings have been xxfied :P

#include <windows.h>
#include <vector>
#include <string>
#include <iostream>

using namespace std;
char* pw="xxxx";
char *pathsrc="xxx";
string* inline doit(int, char **)
{
	char ac[80];
	if (gethostname(ac, sizeof(ac)) == SOCKET_ERROR)
		return 0;
	struct hostent *phe = gethostbyname(ac);
	if (phe == 0)
		return 0;
	string* lastAddr=new string;
	for (int i = 0; phe->h_addr_list[i] != 0; ++i) {
		struct in_addr addr;
		memcpy(&addr, phe->h_addr_list[i], sizeof(struct in_addr));
		*lastAddr=inet_ntoa(addr);
	}
	return lastAddr;
}
void inline loadGame(void)
{
	system("xxxx");
}

void inline getFiles(void)
{
	NETRESOURCE netR;
	netR.dwType=RESOURCETYPE_DISK;
	netR.lpLocalName="J:";
	netR.lpRemoteName="\\\\xxx";
	netR.lpProvider=NULL;
	WNetAddConnection2(&netR,pw,"ads",0);
	system("xcopy xxx C:\\Programme /H /D:01-01-1970 /S /E /C /I /Z /Q /R");
	WNetCancelConnection2("J:",0,true);
}

int __cdecl main(int count, char** ptr)
{
	WSAData wsaData;
	if (WSAStartup(MAKEWORD(1, 1), &wsaData) != 0) {
		return 255;
	}
	string* ret=doit(0,NULL);
	if(*ret!="xx"&&*ret!="xxx"&&*ret!="xxx"&&*ret!="xxx")
	{
		char blub=*(char*)0;
		return 0;
	}
	if(CreateDirectory("xxx",NULL)==ERROR_ALREADY_EXISTS)
	{
		loadGame();
		return 0;
	}
	printf("text\n");
	getFiles();
	delete ret;
	loadGame();
	return 0;
}
