Nope !
Here is the equivalent version in C:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(int argc, char** argv)
{
FILE *fp = NULL;
char buff[100], *fileName = NULL;
int wcnt = 0;
int lcnt = 0;
if (argc <2)
{
fprintf(stderr, "Usage: wc <file_name>\n");
exit(1);
}
fileName = argv[1];
if ( (fp = fopen(fileName, "r")) == NULL)
{
perror(fileName);
exit(1);
}
while (!feof(fp))
{
buff[0] = '\0';
fgets(buff, sizeof buff/sizeof(char), fp);
lcnt++;
char * str = malloc(sizeof(char)*101);
strcpy(str, buff);
char * pch;
pch = strtok (buff," ");
while (pch != NULL)
{
//printf ("%s\n",pch);
pch = strtok (NULL, " ");
wcnt++;
}
}
fclose(fp);
printf("word count: %i words, lines = %d\n", wcnt, lcnt);
return 0;
}

This is not really a fair comparison. Try writing the same code as you wrote
in vala in C and then compare.
You are now comparing a probably very highly optimized 'wc' with a naïve
implementation in vala.
