optional int32 does not get packed or unpacked .

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Delcare optional int32 in .proto file.
2. set the optional field.
3. pack it.
4. unpack it.
5. get the optional field.

What is the expected output? What do you see instead?
I was expecting the optional field back. But it is always the default value(0) .

What version of the product are you using? On what operating system?
version: libprotoc 2.3.0
os: fedora core 10

Look in the .h file that is produced from your .proto file and you will see the 
structure generated to be filled in.  In that structure there is a field called 
has_(name of optional field) that must be set to true (or 1) in order for the 
macros to pack and unpack the optional field correctly.  It appears that this 
is not done automatically, but instead must be done manually.

Set that variable, try it again and see if it works.

Yes, I was wrestling with this for a while today too! Setting the member to 
true fixed it for me.

Yes - you must set the has_ member to nonzero for the member to be packed.
