Note that OMake (as of version 0.9.8) parses command lines internally 
and the thing that is printed is more or what it got _after_ parsing 
(improving the command line printouts is on our "to do list"). Also note 
that the \ before " in the OCAML_LINK_FLAGS line is interpreted 
essentially in the same way a shell would do it - as indication that 
quotes should _not_ be interpreted in any special way and the spaces 
between should retain their usual meaning.

Basically, you are asking OMake to run

ocamlc.opt -warn-error A -g -I . -custom -o hello.run ask.cmo color.cmo 
draw.cmo font.cmo labeltype.cmo box.cmo widget.cmo window.cmo hello.cmo 
valuator.cmo libofltk.a -cclib \"-lstdc++ -L/usr/local/lib -lfltk2 -lX11 
-lXi -lm -lsupc++\"

And you are getting the exact same error that you would get if you ran 
the above line in a shell.

P.S. Using the OMake's internal quotation syntax $"..." is a slightly 
cleaner way of quoting white space than "...". It does not matter if all 
you want is to use the value on the command line, but it does matter if 
you want to use it in OMake functions, as the "..." form would not only 
quote the whitespace in between, but would also include the quotes 
themselves in the value.

For example, consider the following in osh:

% cd /tmp/
% file ($"a b")
- : /tmp/a b : File
% file ("a b")
- : /tmp/"a b" : File
% touch $(file "a b")
% ls -l $(file "a b")
-rw-r--r--  1 anogin wheel 0 Feb 12 09:10 "a b"
% touch $(file $"a b")
% ls -l $(file $"a b")
-rw-r--r--  1 anogin wheel 0 Feb 12 09:11 a b
% ls -l *$"a b"*
-rw-r--r--  1 anogin wheel 0 Feb 12 09:10 "a b"
-rw-r--r--  1 anogin wheel 0 Feb 12 09:11 a b
% ls -l *"a b"*
-rw-r--r--  1 anogin wheel 0 Feb 12 09:10 "a b"
-rw-r--r--  1 anogin wheel 0 Feb 12 09:11 a b
% ls -l $(file a b)
/bin/ls: a: No such file or directory
/bin/ls: b: No such file or directory
