 I am just trying to install GLADE for GNAT 3.10p on my
 RS-6000 running AIX 3.2.
 Since I could not find a binary distribution of GNAT
 for this old machine, I am trying to install GNAT 3.10p
 by bootstraping. I have installed a binary version of
 GNAT 3.05 and now try to compile GNAT 3.07 (the oldest source
 distribution I could find)

 gnat 3.07 says I need GCC 2.7.2 --- I got the sources of gcc 2.7.2
 gnat 3.07 says I have to apply some patches to the sources of gcc 2.7.2
 Citation of gnat's README:
"  -- Apply patches (gcc-272.dif) from the src directory. "

 The file "gcc-272.dif" and has a content like:

*** cse.old     Thu Nov 16 15:49:11 1995
--- cse.c       Sun Nov 26 22:37:16 1995
*************** cse_basic_block (from, to, next_branch,
*** 8405,8408 ****
--- 8405,8409 ----
    int to_usage = 0;
    int in_libcall_block = 0;
+   int num_insns = 0;

    /* Each of these arrays is undefined before max_reg, so only allocate
*************** cse_basic_block (from, to, next_branch,

 and so on ........

 It looks to me as if I have to start some program
 with some options to apply these "patches"
 but what program? and what options?


 ????? What do I do with this File ?????
