GnuPG 1.0.5 mpi build problems on Solaris

[Jos Backus]

I am having some problems getting the i386 mpi assembly code to build on
Solaris 2.[78]. I am using gcc-2.95.3 and Sun's as.

gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../include    -g -O2 -Wall  -c _mpih-mul1.s
Assembler: 
        aline 112       : syntax error
        aline 116       : Illegal register
        aline 116       : syntax error
        aline 117       : Illegal register
        aline 117       : syntax error
[etc.]

This is because cpp by default puts spaces around expanded symbols, which
Sun's as doesn't like:

     pushl     % edi
     pushl     % esi
     pushl     % ebx
     pushl     % ebp

     movl       20 (%  esp   )  , % edi
     movl       24 (%  esp   )  , % esi
     movl       28 (%  esp   )  , % ecx
     movl       32 (%  esp   )  , % ebp

I "fixed" this by using cpp in -traditional mode (cpp by default assumes a
C-like language):

(Of course this isn't the proper fix. configure needs to be taught to use this
switch when defining $CPP but I am not sure how to do that, sorry).

Also, the Sun assembler doesn't like parentheses in the argument to .align:

 #endif

This leaves me with:

gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../include    -g -O2 -Wall  -c _mpih-add1.s
Assembler: 
        "_mpih-add1.s", line 132 : Syntax error
gmake: *** [mpih-add1.o] Error 1

where the offending line is

    leal    (Loop - 3)(%eax,%eax,8),%eax

(It doesn't like the PIC variant either, btw).

I know I can build gpg with without the assembly code, I was just wondering if
anybody else has gotten this to work.

Thanks,
