# {g,n}awk script to generate signames.c

# This version relies on the previous output of the preprocessor
|
|
# on sigtmp.c, sigtmp.out, which is in turn generated by signames1.awk.

# NB: On SunOS 4.1.3 - user-functions don't work properly, also \" problems

# Without 0 + hacks some nawks compare numbers as strings
