# Edited version of Src/signames2.awk.
|
|
#
|
|
# {g,n}awk script to generate errnames.c
|
|
# This version relies on the previous output of the preprocessor
|
|
# on sigtmp.c, sigtmp.out, which is in turn generated by errnames1.awk.
|
|
#
|
|
# NB: On SunOS 4.1.3 - user-functions don\'t work properly, also \" problems
|
|
# Without 0 + hacks some nawks compare numbers as strings
|
|
#
