Dickey 2000 35# 36# Given the choice between constructs such as 37# 38# #if defined(foo) && foo 39# #if foo 40# 41# we chose the latter. It is guaranteed by the language standard, and there 42# appear to be no broken compilers that do not honor that detail. But some 43# people want to use gcc's -Wundef option (corresponding to one of the less 44# useful features in Watcom's compiler) to check for misspellings. So we 45# generate a set of fallback definitions to quiet the warnings without making 46# the code ugly. 47# 48DEFS="${1-ncurses_defs}" 49cat <<EOF 50/* 51 * This file is generated by $0 52 */ 53 54#ifndef NC_DEFINE_H 55#define NC_DEFINE_H 1 56 57EOF 58 59${AWK-awk} <$DEFS ' 60!/^[@#]/ { 61 if ( NF == 1 ) 62 { 63 print "#ifndef", $1 64 print "#define", $1, "0" 65 print "#endif" 66 print "" 67 } else if ( NF != 0 ) { 68 print "#ifndef", $1 69 printf "#define" 70 for (n = 1; n <= NF; n++) { 71 printf " %s", $n 72 } 73 print "" 74 print "#endif" 75 print "" 76 } 77} 78END { 79print "#endif /* NC_DEFINE_H */" 80 } 81' 82
