Tristan Gingold - Sept. 6, 2010, 10:03 a.m.
Hi,

contrary to all other platforms, the default extension for object files
on VMS is .obj.  This is correctly detected by configure stuff so LIBOBJS is
assigned to files with .obj extension.  However the rules are written with
the mostly standard .o extension and thus the build fails.

This patch simply replaces all instances of .o with .$(objext), which looks
to be the standard GNU convention.

I was able to successfully build gcc on x86/Darwin with this patch.

Ok for mainline ?

Tristan.

	* Makefile.in (objext): New variable.
	Replace all occurences of .o with .$(objext)
	* configure.ac (pexecute): Set to the basename.
	* configure: Regenerate.

Yes, that's correct.  But we can't reuse the proposed patch has its author doesn't have an assignment.

You need to adjust maint-tool so that maint-deps still works.  Also, 
please make sure maint-missing still works.

Typo.

Otherwise ok, thanks.
