Subject: Make ao_cmd_decimal produce both 32 and 16 bit values.
X-Git-Tag: debian/0.6+53+gcd49847~2
X-Git-Url: https://git.gag.com/?p=fw%2Faltos;a=commitdiff_plain;h=c671a3f31f54715284beef5baa4a72ca922e4018

Make ao_cmd_decimal produce both 32 and 16 bit values.

ao_cmd_lex_u32 is produced in addition to ao_cmd_lex_i so that
functions can easily read 32-bit values from the command line.
