doubt in C reg. Local function definition

[Aravind Perumal]

Hi

   can any of u let me know Y gcc compiler not giving warning if i  define a function with in a function.

ex:-

    #include <stdio.h>

    int main()   {

                       int x=10;

                      int  show() {

                     int w; 

                     printf ( " inside function \n");

                     return 55;

                    }

         printf("   ret value =>  %d  ", show() );

         return 0;

    }

  its giving  the expected result.

  is local function allowed ?? ( i am sure it is not  allowed)

  then  Y   its not giving any warning ?

 i compiled in gcc with  -Wall options.

  i compiled in different compilers .

 VC ++ , BC++    --->    giving  warning   ( local function illegal )

  gcc , cc , g++    --->  not giving any warning (  getting result )

   and i checked after preprocessing &  assembling  (  it is coforming show  as a function type )

  is there any problem in gcc compiler ?  (  i checked in different machines )

 

could u clear my doubt?

 

Regards

Aravind
