comments in the database. How to avoid/remove?

I have a database created via sql scripts. These scripts are commented like:
  create table xpto
   ( a number, -- this is a number
     b varchar2(100) -- this is another thing     );

When I exported the database and imported to another tablespace, I've got an error like "missing right parentesis". The problem is the -- comment, and the format of the export, where everything is a single line, so after the first -- everything is a comment.

How can I export the tables without the comments ? Or, how can I import without the errors ?   (even if I import with "ignore errors", still have a blocking error) Or, how can I remove the comments from the table definition in the database?

I'm using Oracle Server 7.3.2.2.0 (almost upgrading to 7.3.2.3)

Thanks in advance
