FYI,

With current master (dace5dd1), the following build warnings appear on Ubuntu 9.10 (x86):

  run-command.c: In function ‘notify_parent’:
  run-command.c:70: warning: ignoring return value of ‘write’,
declared with attribute warn_unused_result
  run-command.c: In function ‘die_child’:
  run-command.c:80: warning: ignoring return value of ‘write’,
declared with attribute warn_unused_result
  run-command.c:81: warning: ignoring return value of ‘write’,
declared with attribute warn_unused_result
  run-command.c:82: warning: ignoring return value of ‘write’,
declared with attribute warn_unused_result

These warnings were introduced by the following commits:

  2b541bf8 ("start_command: detect execvp failures early")
  a5487ddf ("start_command: report child process setup errors to the
parent's stderr")

The GCC details are:

  ~$ gcc --version
  gcc (Ubuntu 4.4.1-4ubuntu9) 4.4.1
