more gcc problems

[Sam S. <sd...@gn...>]

gcc (GCC) 3.3.1 (cygming special)
has problems compiling CLISP in MINGW (-mno-cygwin) mode:

 - with default options (./configure build-O-mingw), I get segfault
   during first (load "init.lisp"):

;; Loading file defseq.lisp ...
;; Loaded file defseq.lisp
;; Loading file backquote.lisp ...
*** - handle_fault error2 ! address = 0xa not in [0x19d90000,0x19d90000) !
SIGSEGV cannot be cured. Fault address = 0xa.

   (of if I copy *.fas, I get "*** - Program stack overflow. RESET" when
    compiling compiler.fas)

 - when I remove -O2 -fexpensive-optimizations -fomit-frame-pointer, I get 
C_CODE_ALIGNMENT is wrong. &EVAL-WHEN = 0x43301e.
Add -falign-functions=4 to CFLAGS in the Makefile.

 - when I add "-falign-functions=4" to CFLAGS, everything works.

 - when I replace it with "-O2", everything works.

 - "-O2 -fexpensive-optimizations" ==> everything works.

 - "-O2 -fomit-frame-pointer" ==> same crash.

 - "-O2 -fexpensive-optimizations -fomit-frame-pointer" ==> same crash

 - "-falign-functions=4 -fomit-frame-pointer" ==> works!!!

I guess we should disable -fomit-frame-pointer for gcc 3.3,
but someone has to report the bug - if indeed this is a bug.
