[bug-gawk] Handling hexadecimals in different modes

[Jarno Suni]

gawk 'BEGIN{printf("%d\n", "0x15")}';
gawk -W non-decimal-data 'BEGIN{printf("%d\n", "0x15")}';
gawk -W traditional 'BEGIN{printf("%d\n", "0x15")}';
gawk -W posix 'BEGIN{printf("%d\n", "0x15")}';
(prints 0, 21, 0, 21, respectively)

I wonder why it works different way in traditional mode than in posix
mode. I didn't find it in documentation. I am going to write a script
that works the same way, no matter if gawk or mawk is the available awk
implementation.

These two
mawk -W non-decimal-data 'BEGIN{printf("%d\n", "0x15")}';
mawk -W posix 'BEGIN{printf("%d\n", "0x15")}';
work same way than with gawk (albeit a warning message with the first
command written to standard error).
