libcgg2.c junk characters - compile error

[Zrinka Bilusic <zrinka at ucla dot edu>]

Hi,
I am trying to compile gcc 2.95.3 (or 2.95.2 - whichever works) on my 
mac running OS X 10.1. I decided to do this after I realized that my 
version of cc (apple's mutant of gcc 2.95.2) does not have standard c++ 
libraries that I needed to compile another package. But I run into some 
strange problems. The compilation exists with the following error:

Now, when I look at the libgcc2.c at line 156 here is what i find (these 
are lines 156 - 191; notice strange ^L characters):
---------------------------
#endif
^L
#if defined (L_negdi2) || defined (L_divdi3) || defined (L_moddi3)
#if defined (L_divdi3) || defined (L_moddi3)
static inline
#endif
DItype
__negdi2 (DItype u)
{
   DIunion w;
   DIunion uu;

   uu.ll = u;

   w.s.low = -uu.s.low;
   w.s.high = -uu.s.high - ((USItype) w.s.low > 0);

   return w.ll;
}
#endif
^L
/* Unless shift functions are defined whith full ANSI prototypes,
    parameter b will be promoted to int if word_type is smaller than an 
int.  */
#ifdef L_lshrdi3
DItype
__lshrdi3 (DItype u, word_type b)
{
   DIunion w;
   word_type bm;
   DIunion uu;

   if (b == 0)
     return u;

   uu.ll = u;

---------------------------------------------------------------

I tried doing several things - I tried commenting them out (all of 
them - there are more of those further down the file), deleting them, 
deleting a line before and after and retyping - nothing worked. I even 
tried commenting out a whole piece of code between lines 100 and 300 but 
I was still getting the same error - reported at the same line in the 
code. Then I thought it might have been the result of unpacking and 
decompressing with 'stuffit expander' so I downloaded again and did 
gunzip and tar xvf from the command line - still the same characters in 
the same place. Then I downloaded gcc 2.95.2 and 3.0.2 and looked at 
their libgcc2.c - same thing. I downloaded all from 
ftp://ftp.mirror.ac.uk/sites/sourceware.cygnus.com/pub/gcc/releases/.
I successfully installed gcc 2.95.3 on an alpha some months ago and I 
don't remember having any problems. (unfortunately I have deleted the 
source since then so I could not find libgcc2.c there). What do I do at 
this point? I will probably try to download from another place (I tried 
the main ftp site yesterday but it kept asking me for a login and 
password - that was the first time that happened - that's why I found a 
mirror site).  One other note - to compile 2.95.3 or 2.95.2 I had to run 
configure with i386-apple-freebsd (configure with no options would not 
recognize the target). Could that cause problems?
A few more questions about 3.0.2. I tried that version initially but ran 
into different problems. configure recognized the target as 
powerpc-apple-darwin1.4, but then during build (it actually never got as 
far as 2.95.2.3) there was an error in function.c (see below). At that 
point I decided to go with 2.95.2 since cc that I have is based on that 
and I thought it would be easier - and then later build 3.0.2 using 
2.95.2. I also had a message during configure of 3.0.2 (*** This 
configuration is not supported in the following subdirectories: 
target-libffi target boehm-gc target-zlib target-libjava (Any other 
directories should still work fine.) ) that I did not quite understand. 
What is this warning and how does it affect the configure/build/install 
processes?

Any thoughts, hints.. would be greatly appreciated. Thank you!!
