Why do I get "illegal statement termination" compile-time errors when building a C source file with MBUILD in MATLAB Compiler 4.9 (R2008b)?

I have simple C-file and the code is provided below:

 #include <stdio.h>

 int main() {

     printf("Hello World \n");

     int a;

     return 0;

 }

When I try to create a standalone application from the C-file using MBUILD, I receive the following error messages:

 Error T:\1-83SFP9\FORSWA~1\trial.c: 5  illegal statement termination 

 Error T:\1-83SFP9\FORSWA~1\trial.c: 5  skipping `int' 

 Error T:\1-83SFP9\FORSWA~1\trial.c: 5  undeclared identifier `a' 

 Warning T:\1-83SFP9\FORSWA~1\trial.c: 5  Statement has no effect 

 Warning T:\1-83SFP9\FORSWA~1\trial.c: 5   possible usage of a before definition

The error occurs because in ANSI C, all variables must be declared at the beginning of a function before any other executable statements. To resolve the issue, modify the code as shown below:

 #include <stdio.h>

 int main() {    

 int a;

 printf("Hello World \n");

     return 0;

 }
