[Bug c++/21656] New: Spurious "template with C linkage" error message

[pkoning at equallogic dot com]

This test program:

# 1 "test.cc"
# 1 "np.h" 1
# 1 "Math.h" 1 3 4
template<class T> static inline void push(T* element, T** head)
{
 element->m_flink = *head;
 *head = element;
}

produces:

In file included from test.cc:2:
Math.h:1: error: template with C linkage

If I delete the "# 1 "Math.h" 1 3 4" then it works.

Strangely enough, it also works on different builds of the same version: for
example, the native (i386) build, as well as a build targeted to
mipsel-netbsdelf, both accept the test program without complaint.

The failing compiler's --verbose output is:

mips64el-elf-g++ --verbose

This is a target problem, it is not defining NO_IMPLICIT_EXTERN_C.

Thanks.  I added that to config/mips/elf.h and it works correctly now.

OK, I'll run that change through dejagnu and commit if there are no problems.

Committed to mainline.

Let me know if this is a regression from an earlier release.  I'll then apply
the patch to the appropriate branches.  I'll tentatively close this PR as fixed
in the meantime.
