Generated code does not compile: missing implementations

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Update to -r151
2. Generate code for any WS
3. Add code to project and compile

What is the expected output?
A successful compilation

What do you see instead?
Undefined symbols:
  ".objc_class_name_Service1_GetMyIPhoneResponse", referenced from:
      literal-pointer@__OBJC@__cls_refs@Service1_GetMyIPhoneResponse in 
Service1.o
  ".objc_class_name_Service1_SubmitReportResponse", referenced from:
      literal-pointer@__OBJC@__cls_refs@Service1_SubmitReportResponse in 
Service1.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

What version of the product are you using? On what operating system?
WSDL2Objc -r151 from SVN

Please provide any additional information below.
I double checked against an older code generated by another revision of 
the code (probably from -r142, don't remember correctly) and the code did 
have the @implementation lines for those classes that are mentioned as 
missing.

I've just generated code with -r145 and it works perfectly. Didn't try any 
further 
versions.
