Solaris 2.6; Netscape Enterprise Server 3.6.
Php interpreter built for installation outside Webserver document tree, with leading #! line in CGI script used to activate interpreter. This line appears as first line of the generated HTML. 

N.E.S. config statements:
 In mime.types:
  type=magnus-internal/cgi exts=php4
 In obj.conf:
  <Object name="default">
  .
  .
  Service fn="send-cgi" type="magnus-internal/cgi"
  .
  </Object>

This appears to be same situation reported for other webservers in bug reports 8506 and 8782.

sapi/cgi/cgi_main.c has code to check and skip leading #! line, but it is controlled by previous "if" clause which is present to set up reading interpreter input from script file in cgi environment. Making #! checks whenever input is from file fixes problem under CGI and is OK as well using same interpreter in standalone mode.

Suggested diff based on 4.0.4pl1 source (in effect just deletes an "else"):
