Re: [Mingw-users] where is the document of "__attribute__((com_interface))"

[Luke D. <cod...@ho...>]

Apparently this attribute was not documented yet in GCC version 2.95.3, so a
quick Google search reveals:

http://www.la.utexas.edu/lab/software/devtool/gnu/gcc/gcc_121.html

Apparently this page refers to GCC version 2.97 (?), which was probably not
an official release, but it should be okay. If this documentation is not
enough then read some of the other pages that Google finds.
