You are assuming that `fread' appends an extra `\0' (null) character to
the buffer after it reads the file.  This is false.  So when `printf'
looks for the trailing `\0', which %s format requires, it happily runs
beyond the end of data[] and prints what's left from the DJGPP.ENV
processing by the startup code.
