Here's what I get around the offending lines with both gcc-3.4.3 and  
gcc-4.2.3 on
mips-sgi-irix6.5:

    while (__builtin_va_arg(tmp_authors,const char *) != 0L)
      ++n_authors;

And with MIPSpro 7.4.4m cc -E on the same machine:

    while (((const char * *)(void *)( tmp_authors = ( va_list)  
(( ( ((__va_iptr_
t)tmp_authors)+((__NO_CFOLD_WARNING( (__builtin_alignof(const char *)  
> 8) ? (__
va_iptr_t)__builtin_alignof(const char *) : (__va_iptr_t)8 ))-1) ) & (- 
(__NO_CFO
LD_WARNING( (__builtin_alignof(const char *) > 8) ?  
(__va_iptr_t)__builtin_align
of(const char *) : (__va_iptr_t)8 ))) )+ 
(__NO_CFOLD_WARNING( ((__builtin_classof
(const char *) == 0) && (sizeof(const char *) < 8)) ? 8-sizeof(const  
char *) : 0
 ))+sizeof(const char *)) )) [-1] != 0L)
      ++n_authors;

Where in the gcc -E output you sent me, I see:

    while (((const char * *)(void *)( tmp_authors = ( va_list)  
(( ( ((__va_iptr_
t)tmp_authors)+((__NO_CFOLD_WARNING( (__builtin_alignof(const char *)  
> 8) ? (__
va_iptr_t)__builtin_alignof(const char *) : (__va_iptr_t)8 ))-1) ) & (- 
(__NO_CFO
LD_WARNING( (__builtin_alignof(const char *) > 8) ?  
(__va_iptr_t)__builtin_align
of(const char *) : (__va_iptr_t)8 ))) )+ 
(__NO_CFOLD_WARNING( ((__builtin_classof
(const char *) == 0) && (sizeof(const char *) < 8)) ? 8-sizeof(const  
char *) : 0 ))+sizeof(const char *)) )) [-1] != 0L)
      ++n_authors;

So it looks very much like you're somehow feeding the output of the  
MIPSpro preprocessor to your gcc .  I'd say you need to reinstall gcc  
and try again.

Cheers,
        Gary
