Actually, I should open a bug ticket for the developers of VC 2015, I
guess. I am using Visual Studio Pro Web 2015 RC at the moment.
Compilation of even deplister.exe is broken in this compiler with a
'unresolved external symbol _printf'. I created a real simple example of
the same error. See the following console output:
|C:\php-sdk>type windowsh.c
|
|#include <windows.h>
|
|int main( int argc, char* args[] ) {
| printf("Testing");
| return 0;
|}
|
|C:\php-sdk>cl.exe /Fewindowsh.exe windowsh.c

|
|/out:windowsh.exe
|windowsh.obj
|windowsh.obj : error LNK2019: unresolved external symbol _printf referenced in function _main
|windowsh.exe : fatal error LNK1120: 1 unresolved externals
If I #include <stdio.h> compilation goes fine:
|C:\php-sdk>type stdioh.c
|
|#include <stdio.h>
|
|int main( int argc, char* args[] ) {
| printf("Testing");
| return 0;
|}
|C:\php-sdk>cl.exe /Festioh.exe stdioh.c

|/out:stioh.exe
|stdioh.obj
|
|C:\php-sdk>stioh.exe

This might be a recent change in VC 2015. It looks like they are still
changing a lot in it. Not ideal to build alpha's with a moving compiler.
