 After a compilation error chicken-install will continue to execute and
 attempt to install the extension anyway.

 For example, install the readline egg without any readline library
 installed at all:

 {{{
   /home/jim/local/chicken-4/bin/csc -feature compiling-extension   -s -O2
 readline.scm -lreadline -lhistory -ltermcap
 Error: shell command terminated with non-zero exit status 256:
  gcc readline.c -o readline.o -c -fno-strict-aliasing
 -DHAVE_CHICKEN_CONFIG_H -Os \
   -fomit-frame-pointer -fPIC -DPIC -DC_SHARED
 -I/home/jim/local/chicken-4/include

   /home/jim/local/chicken-4/bin/csc -feature compiling-extension   -c -O2
 -d0 -j readline \
    readline.scm -o readline-static.o -unit readline -lreadline -lhistory
 -ltermcap
 Error: shell command terminated with non-zero exit status 256:
  gcc readline-static.c -o readline-static.o -c -fno-strict-aliasing
 -DHAVE_CHICKEN_CONFIG_H \
   -Os -fomit-frame-pointer -I/home/jim/local/chicken-4/include

   /home/jim/local/chicken-4/bin/csc -feature compiling-extension   -s -O2
 -d0 readline.import.scm

   rm -fr /home/jim/local/chicken-4/lib/chicken/4/readline.so
 Error: file does not exist: "readline.so"
 Error: shell command terminated with nonzero exit code 17920
 }}}

 It probably also prevents the correct analysis of which libraries are on
 the system, which was reported by Sam Varner, because a failing compile
 will "succeed" from the caller's perspective.

 Wild guess, this could have to do with improper parsing of exit status 256
 (which happens to be 0 mod 256).  Actual investigation is needed.
