Well, I also do not get an executable, as I reported afew days ago.
I've updated every file available.  However, if it helps,
below I also include the result using "gcc -v"

: David,
: 
: I haven't had a problem with "hello world".  Here's my program and the gcc
: string I used.
: 
: #include <stdio.h>
: 
: main()
: {
:      printf("hello world\n");
: }
: 
: Here's how I compiled it:
: 
: gcc  hello.c   -o hello
: 
: When I run the above gcc command I get the following executable:
: 
: hello.exe
: 
: I run this by typing "hello.exe" at the command promt. It prints "hello
: world" on my screen.
: 
: Perhaps you could use "-v" with gcc to get more verbose output.
: 
: I have in fact run into the problem you're having but only when trying to
: link against a DLL.
: Then I get no warnings, no errors and no executable. I don't yet know why.
: 
: Wish I could tell you more.  I apologize for all the help I've given you
: 8^).
: 
: David
