gdb build failures

[Daron Chabot]

All,

FYI: "Out of the box", gdb-6.7.1 (and gdb-6.8 as well) do not build  
on mac os x (Tiger). The failure is due to the addition of "-Werror"  
to the gdb's build CFLAGS (and maybe also due to the use of  
gcc-4.x.x ?).

Once the build gets to gdb-6.x.x/gdb, it trips over warnings like these:
../../gdb-6.7.1/gdb/i386-tdep.c: In function 'i386_collect_fpregset':
../../gdb-6.7.1/gdb/i386-tdep.c:2035: warning: format not a string  
literal, argument types not checked
../../gdb-6.7.1/gdb/i386-tdep.c: In function 'i386_print_insn':
../../gdb-6.7.1/gdb/i386-tdep.c:2139: warning: format not a string  
literal, argument types not checked

which, of course, cause the build to bail because of the -Werror flag...

In each warning case, the culprit code is one form or another of  
error-reporting or gdb-assert( ) statements. These functions may not  
be dangerous in any way, but gcc seems to think that they *could* be...

Simply removing the "-Werror" addition from the appropriate Makefile  
allows the build(s) to complete successfully, albeit with much noise...

Should the gdb and gcc lists be notified ?
