Misplaced space(s) around '++' sign and Wrong Tabulation in Makefile

[Hugo]

Hello,

When i make nb++ for example, but NormEZ tells me that I have misplaced space(s) around '++' sign, but only there aren't misplaced space(s) around this with this code as for example:
if (test_neg1 == 1) {
my_putchar('-');
nb1++;
nb2++;
}

And in Makefile, there are tabulation, but NormEZ wait for spaces
