I know that 2.3.1 compiled with a configure alpha-dec-osf,
but for some reason, 2.3.3 is giving me the following problem:

BOX: DEC Alpha 3000/400
OS:  OSF/1 1.2 rev 10
LOCAL: 1. configure alpha-dec-osf
       2. changed the verstamp macro to match /usr/include/stamp.h
       3. in rtl.def there is a macro conflict over the meaning of ABS
          which is defined in /usr/include/asm.h to mean:
	    #define ABS(x, y)       
	  which then conflicts with line 713 of rtl.def:
	     /* Absolute value */
             DEF_RTL_EXPR(ABS, "abs", "e", '1')
	  Current hack is an #undef ABS in front of that declare.
	  Don't know if this is a really bad idea or not.
       4. removed the -g items from the Makefile to cut down on warnings
          about "this version doesn't support"
       
make LANGUAGES=c

....(no problems until we hit the first xcc build of libgcc.a)

libmld--as1: Error: /tmp/cc003584.s, line 5: .mask must have pcreg from .frame set if any bits are set in .mask or .fmask

The relevant assembly code being questioned is:

line 266: 
.text
        .align 3
        .globl __udivmoddi4
        .ent __udivmoddi4 2

        lda $30,-32($30)
        .frame $30,32,$26
        stq $9,0($30)
        stq $10,8($30)
        stq $11,16($30)
        stq $12,24($30)
        .mask 0x1e00,-32
        sra $17,32,$28
        sra $16,32,$8
        addl $17,$31,$17

Outside the scope of my knowledge to fix this, and Alpha assembly
wizards? Patch for gcc?
