"char *" of course is not the same as "char []". So I had to fix the way ecpg treated the second one.

Applied patch by Philip Yarra to fix some thread issues.
Added a new data type "decimal" which is mostly the same as our
	"numeric" but uses a fixed length array to store the digits. This is
	for compatibility with Informix and maybe others.

  fixed amount of digits and not an allocated one. So we have to work
  around. PostgreSQL numeric type remains the same.
- In INFORMIX_SE mode with autcommit set, make all cursors be "with
  hold". Is this really they way SE behaves?

- Compatibility functions for INFORMIX handling of DECLARE statement.

Fixed counting bug in parsing "->" operator.
Removed that silly debugging function I accidently committed last night.

ecpg now recognizes named structs/unions. So you don't have to list the whole definition everytime you declare a variable anymore.

Fixed incorrect include and another typo. Sorry, the include did not create a warning/error/problem on my machine, so I didn't notice it.

	- Accept CPP defines for type definitions.
	- Do not parse system include files automatically for Informix mode

Added an option to force ecpg to also parse files includes via '#include' and some more Informix stuff.
