warning/error about possibly uninitialized 'exact' in find_line_symtab

[Jay <jay.krell@cornell.edu>]

I didn't want to deal with the stdint.h issue
I hit in 6.8 so I'm building 6.7.1.
I see now the mail threads where it was fixed pretty simply.
So maybe I'll go back to that.
 
 
In the meantime, with 6.7.1, I hit a simple problem (so far, still compiling)
warning variable 'exact' may be used uninitialized + -Werror.
 
 
Here is my patch:
 
 
-bash-3.2$ gdiff -u symtab.c.orig symtab.c
--- symtab.c.orig 2009-02-22 20:25:52.000000000 -0800

+ int exact = { 0 };

so far seen. */
 
 
Sure, now it may be unoptimally unnecessarily initialized but
I don't think that is worth worrying about.
 
 
I use { 0 } instead of 0 because it is a more generic form that
can zero initialize "anything", except some unions on some compilers,
it might not always zero the entire thing.
 
 
Current source looks about the same.
 
 
My system is:
 
 
-bash-3.2$ gcc32 -v
Using built-in specs.

gdb configured with:

 
$ /src/gdb-6.7.1/configure -disable-nls -prefix=/usr/local/32

 
and I rm -rf /src/gdb*/intl
and maybe altering PATH and/or CC, e.g. CC=gcc32, but gcc first
in $PATH is the same so that shouldn't matter here, by far.
 
 
 
Thanks,
