printf/sprintf-modifier "0" not working in gawk 3.1.8 under Cygwin

[Christian . Matuszewski]

Hi,

I recently ugraded to gawk 3.1.8. and stumbled upon a different behaviour
to gawk 3.1.7.
To reproduce, execute the following program:
BEGIN {
    number = 25
    padded_number = sprintf("%04s", number)
    print(padded_number)
    printf("%04s", 25)
}

With 3.1.7 I get the expected result:
0025
0025

With 3.1.8 I get:
  25
  25

Best regards,

Christian
