Re: strange --version issue

[John Calcote]

Here's some more data on the m4 --version issue.

$ *m4 --version*
*GNU M4 1.4.4*
Written by Rene' Seindal.
...

$ *strace m4 --version*
execve("/usr/local/bin/m4", ["m4", "--version"], [/* 68 vars */]) = 0
...
write(1, "GNU M4 1.4.5\n", 13*GNU M4 1.4.5*
)          = 13
write(1, "Written by Rene\' Seindal.\n\nCopyr"..., 152Written by Rene' 
Seindal.
...

Running "m4 --version" alone appears to execute the one in /usr/bin 
(1.4.4), while executing under strace seems to run the correct one in 
/usr/local/bin (1.4.5).

Again, I'm wondering...
