Thanks for the patch! I have a few preliminary questions and comments...
First, do you or your company have a copyright assignment on file with FSF?
I could be wrong, but I believe adding to config/ will require
approval from a GCC config/ maintainer. The normal process, as I
understand it, would be to add the file to the GCC tree, then sync it
into the binutils tree. I'm not in a position to approve that, nor can
I judge on the acceptability of the copyright notice in that file.
I'd like to retain the ability to use --disable-threads as a configure option.
If this is just to get MinGW on board, is there a lighter-weight way
of doing that? Could we just add a configure option that switches
between -lpthread and -pthread (or whatever option is needed)? I like
the idea of fully automating it, but that's a pretty big m4 file!
Anyway, I'd like to hear what the GCC folks think of adding
ax_pthread.m4 to the config/ directory.
(BTW, In the future, please omit diffs from generated files from your patch.)
