Compiling mozilla-1.2.1 using the tarball and cvs. got to
file

mozilla/nsprpub/pr/src/md/unix/os_SunOS_x86.s

and saw this on my screen:

/usr/ccs/bin/as accepts -b and -s:


  Common Options
     The following flags are common to both SPARC  and  IA.  They
     may be specified in any order:

     -b    Generates extra symbol table information for  
           the Sun SourceBrowser.
...
     -s    Places all stabs in the .stabs  section.  By 
           default, stabs  are placed  in  stabs.excl 
           sections, which are stripped out by the static 
           linker, ld(1), during final execution. When the 
           -s option is used, stabs remain in the final 
           executable because .stab  sections  are  not
           stripped by the static  linker.


It looks like I might need to file a bug/rfe with Sun for
this issue too.


>How-To-Repeat:

throw a .s file at gcc-3.2.1 which is configured to use
/usr/ccs/bin/as, and use the "-gstabs" option to gcc
>Fix:

reconfig gcc to not use /usr/ccs/bin/as, and
get Sun to fix /usr/ccs/bin/as so it doesn't die when passed
options is doesn't accept.
