This patch uses a C program to build an index(.help.index). The script then
uses this index to extract the help for the CONFIG_* variables. When the index
is built, the mmap'ed Configure.help is stepped through, line by line, and an
index of the form "<config-var> <start-offset> <end-offset>" is built in
.help.index. When extracting help, strstr is used on a mmap'ed .help.index, and
then extracted from a mmap'ed Configure.help.
This code doesn't handle errors to well. If extract is called, without
.help.index existing, it segfaults. Also, if an error happens when open a file,
mmap'ing, etc, it doesn't exit gracefully. Other than that, the script speeds
up help extraction.
Linux vs. Windows is a no-win situation.
