| Subject: | INIT block not executed in Win32::API::Type when 'require' used |
INIT blocks do not get executed when modules are imported using 'require':
Too late to run INIT block at C:/perl5/site/5.8.7/lib/MSWin32-x86-multi-thread/Win32/API/Type.pm line 71.
This is a significant problem for modules that want to optionally support Win32 features.
The INIT block and __DATA__ section should be replaced by coding in the data directly. I have attached a patch to do this.
