(observed on an rs/6000 running aix:) Gcc uses mktemp() to generate
"random" names for temporary files; these names may contain '%'.
These filenames are passed to gld as arguments.  Unfortunately, gld
does not recognise '%' as a valid filename character:

from ldlex.l:
CMDFILENAMECHAR   [_a-zA-Z0-9\/\.\\_\+\$\:\[\]\\\,\=\&\!\<\>\-\~]
CMDFILENAMECHAR1  [_a-zA-Z0-9\/\.\\_\+\$\:\[\]\\\,\=\&\!\<\>\~]

I added % to these productions as follows:
CMDFILENAMECHAR   [_a-zA-Z0-9\/\.\\_\+\$\:\[\]\\\,\=\&\!\<\>\%\~\-]
CMDFILENAMECHAR1  [_a-zA-Z0-9\/\.\\_\+\$\:\[\]\\\,\=\&\!\<\>\%\~]

I did not add % to productions for FILENAMECHAR or FILENAMECHAR1
because I was concerned that it might make the parser unable to
recognize some arithmetic expressions.  However, this leaves the
program with strange semantics: some filenames can be referenced from
the command line but not the script language!
