+# Sed script to parse CPP macros and generate output usable by make
+#
+# It is expected that this script is fed the output of 'gpp -dM'
+# which preprocesses the common.h header files and outputs the final
+# list of CPP macros (and whitespace is sanitized)
+#
+
+# Only process values prefixed with #define CONFIG_
+/^#define CONFIG_[A-Za-z0-9_][A-Za-z0-9_]*/ {
+ # Strip the #define prefix
+ s/#define *//;
+ # Change to form CONFIG_*=VALUE
+ s/ */=/;
+ # Drop trailing spaces
+ s/ *$//;
+ # drop quotes around string values
+ s/="\(.*\)"$/=\1/;
+ # Concatenate string values
+ s/" *"//g;
+ # Assume strings as default - add quotes around values
+ s/=\(..*\)/="\1"/;
+ # but remove again from decimal numbers
+ s/="\([0-9][0-9]*\)"/=\1/;
+ # ... and from hex numbers
+ s/="\(0[Xx][0-9a-fA-F][0-9a-fA-F]*\)"/=\1/;
+ # Change '1' and empty values to "y" (not perfect, but
+ # supports conditional compilation in the makefiles
