To compile gcc-2.2.2 under AIX PS/2 you need a patch for gcc (include at
the end of this message) and a modified version of gas-1.92.3 (alpha).
I can put somewhere for anonymous ftp my whole gas-1.92.3 compiled if 
somebody has space.  Or I can mail the diff for gas-1.92.3 to whoever 
wants it.

Minh Tran-Le.

note: if you have aix ps/2 up to the latest patch you can enable linking
      gcc with shared libraries by uncommenting BOOT_LDFLAGS in:
      config/t-aix386.
