Bug #1265: test_import calls printf in different c runtime libraries

On Windows, test import loads msvcrt.dll and then calls printf. That only works with mingw or VC6. Any newer version of VC will cause a segmentation fault since you cannot mix file handles across runtime libraries.

Patch causes test to not be run on Windows.

Hi Usaku,

I tried the same approach before submitting my patch, put it doesn't work:

ruby test_dl2.rb:

1. Error:
   test_empty(DL::TestBase):
   DL::DLError: Invalid argument
   C:/Development/src/ruby_trunk/test/dl/test_base.rb:65:in initialize' C:/Development/src/ruby_trunk/test/dl/test_base.rb:65:in dlopen'
   C:/Development/src/ruby_trunk/test/dl/test_base.rb:65:in `setup'

Not a very helpful error message, but it seems like you can't dynamically load msvcr90.dll (or if you can it doesn't work for me).

Also, in your logic, instead of this:

libc_so = libm_so = RbConfig::CONFIG["RUBY_SO_NAME"].split(/-/, 2)[0] + ".dll"

Could you do this:

libc_so = libm_so = RbConfig::CONFIG["sitearch"].split(/-/, 2)[1] + ".dll"

Thanks,

Charlie

1. Error:
   test_call_double(DL::TestDL):

Etc....

The new code loads ruby19.dll. Is that what you mean to do? Or were you trying to
