It seems so :)

The following two lines are from the linux man page of 
is[xxx] set of functions.

isblank()
	checks for a blank character; that is, a space or a tab.  This function
is a GNU extension.

I think reason for this function to be missing is that is
a GNU extension. However you can implement that function by
yourself pretty easy :)

int isblank(int c)
{
    if (c != ' ' && c != '\t')
	return 0;
    
    return c;
}
