The gcc driver has support to convert arbitrary long options into -f 
options.  So for instance --test-coverage gets converted to 
-ftest-coverage.  See the last entry of the option_map table which 
performs this magic.  This was added for POSIX support, as POSIX has 
some special rules for how command line options work, but -- options are 
always safe in POSIX.

If you have something like "--<special-character>" on the command line, 
the gcc driver would convert that to a -f option, and then cc1 would 
complain that "-f<special-character>" is not a recognized option.  It 
does look like you have some spurious -- characters on your gcc command 
line.  Maybe one of them is followed by a non-printing non-white space 
character?

I wonder if this -- to -f conversion feature is documented anywhere.  It 
probably isn't.  Also, the option_map table is probably long out of 
date, because it is supposed to list every option that doesn't start 
with -f, or which requires arguments.  Otherwise, gcc won't be fully 
compliant with the POSIX rules for command line arguments.
