when the commented line remains commented, the application compiles

akcom, this code works:

# // winapi1.d
# // To Complie: dmd winapi1.d
# // Tested on WinXP SP2, with dmd v0.141
# private import std.stdio;
# private import std.c.windows.windows;
# 
# extern( Windows )
# HMODULE GetModuleHandleW
# (
#   /+ IN  +/ LPWSTR lpModuleName
# );
# 
# extern( Windows ) 
# DWORD GetModuleFileNameW
# (
#   /+ IN  +/ HMODULE hModule,
#   /+ OUT +/ LPWSTR  lpFilename,
#   /+ IN  +/ DWORD   nSize
# );
# 
# // std.c.windows.windows only has the ASCII version defined:
# // DWORD GetModuleFileNameA(HMODULE hModule, LPSTR lpFilename, DWORD nSize);
# 
# wchar[] getModuleFileName( in HMODULE hModule )
# {
#     wchar[] wResult;
# 
#     wResult.length = 256;
#     wResult.length = 
#         GetModuleFileNameW( hModule, &wResult[0], wResult.length ); 
# 
#     return wResult;
# }
# 
# int main()
# {
#     // If this parameter is NULL, GetModuleHandle returns a handle to the 
#     // file used to create the calling process (.exe file).
#     writefln("Module filename=\"%s\"", getModuleFileName( cast(HMODULE)null
));
#     return 0;
# }

Output:

IIRC there isn't a guarantee that the first arg is your executable name.  
Granted most (maybe all existing) prompts/shells define it so, but I  
suspect it's a habit as opposed to a guarantee.

For example you can write an app which executes the above binary using  
'execve' and does not assign the executable filename to the first arg.
