[CM] Weirdness with s7_load_c_string_with_environment, xxd fun

[bil at ccrma.Stanford.EDU]

Thanks for the example -- I had to add #include <string.
I get the error "string is not terminated".  xxd -i generates
an array that does not end with 0, so when it's cast to
a C string, it is not terminated.  The example scheme code
for make-repl-bits.scm adds that 0 at the end (see also
nrepl-bits.h).  If i add the ending 0's to the 2 resources
(leaving the length alone because it's viewed as a c string
length), your program appears to work.
