The gdc.test/compilable/ddoc12.d test FAILs when using Solaris as:

FAIL: compilable/ddoc12.d   output-exists ddoc12.o

On sparc, one sees

while on i386 I get:

The problem obviously is that the native assemblers don't support UTF-8 in
identifiers (and I bet there are other non-gas assemblers that don't either).

Besides, we again see the obnoxious effect of gdc-test.exp's 

// { dg-prune-output .* }

which effectively masks all errors, letting the test for excess errors wrongly
PASS.
