problem compiling gdb5.0 on NetBSD-current i386 ELF

[blymn at baesystems dot com dot au (Brett Lymn)]

Folks,
        I just attempted to compile gdb5.0 on a NetBSD-current i386
ELF machine and the thing fell over compiling gdb/solib.c.  The uname
of my machine gives:

NetBSD siren 1.4X NetBSD 1.4X (SKEL) #0: Mon May 15 18:20:37 CST 2000
   toor@siren:/usr/src/sys/arch/i386/compile/SKEL i386

My gcc version is this:

gcc version egcs-2.91.66 19990314 (egcs-1.1.2 release)

and the errors I get are these:

The interesting thing about this is if I look at the lines that have
the error about som_addr on them I see this:

      p->addr += LM_ADDR (so);

which use these defines from the top of the file:

#define SOLIB_EXTRACT_ADDRESS(member) \
  extract_address (&member, sizeof (member))

#ifndef SVR4_SHARED_LIBS

#define LM_ADDR(so) (SOLIB_EXTRACT_ADDRESS ((so) -> lm.lm_addr))


_but_ if I look at the preprocessor output I see:

      p->addr += (extract_address (& ( so ) -> lm. som_addr  , sizeof
( ( so ) -> lm. som_addr  )) ) ;


somehow the lm_addr's have been changed into som_addr which is very odd.
