All -  
I have resolved most of the problems encountered during “make  
check”; it seems the test runs do not honor LD\_LIBRARY\_PATH, so I had  
to symlink the libraries for openssl, gdbm and ncurses to /lib, and  
then my results look like this

```
  Finished in 73.679603 seconds.

```

So it appears that most of the compiler warning messages are in fact  
harmless. I would like to understand though why “–enable-pthread”  
causes the backtrace error in eval.c:

eval.c  
“eval.c”, line 4482: warning: statement not reached  
“eval.c”, line 4517: warning: statement not reached  
“eval.c”, line 4644: warning: statement not reached  
“eval.c”, line 4702: warning: statement not reached  
“eval.c”, line 5151: warning: statement not reached  
“eval.c”, line 5614: warning: statement not reached  
“eval.c”, line 5740: warning: statement not reached  
“eval.c”, line 6251: identifier redeclared: backtrace  
current : static function() returning unsigned long  
previous: function(pointer to pointer to void, int)  
returning int : “/usr/include/execinfo.h”, line 41  
“eval.c”, line 8612: warning: loop not entered at top  
“eval.c”, line 12004: warning: statement not reached  
“eval.c”, line 12446: warning: statement not reached  
“eval.c”, line 12818: warning: statement not reached  
cc: acomp failed for eval.c  
gmake: \*\*\* [eval.o] Error 2

It seems to modify the includes such that /usr/include/execinfo.h gets  
included, when without the “–enable-pthread” it doesn’t (or some  
other define “hides” the definition of backtrace).
