Your patch is correct and I will apply it today. "rb" should not be used with 
popen(), because popen() is not ANSI compatible and the "b" flag is not 
recognized (and may cause problems in some platforms).

However, I do not want to change the definitions of OPEN_R. The current values 
have been very useful when porting ECL to other platforms (For instance in 
Cygwin, and MacOSX at the very beginning), and should be recognized by any 
POSIX-compliant platform. In other words, the least platform-dependent 
#ifdefs, the better :-)
