# The "BINARY SIZE +=" comments note about how much bulk, in kilobytes, a
# given option adds to the binary on x86 Linux (built with gcc 3.3.6
# MinSizeRel options and stripped, uncompressed). These numbers will vary,
# and even on the original test system, become incorrect over time.
# Only choose options you want/need to squeeze every byte off the download.
