get the location of the definition of expression's type?

get the location of the definition of expression's type?

[zet]

Hello, All

When (gdb) ptype global_options
I will get definition of the type of global_options whose type is
'struct gcc_options'

Is it possible get the definition location(which file it is defined
in) info  of 'struct gcc_options'?

I know the line info of 'struct gcc_options' in ELF may lose, but is
gdb has the facility show the line info of the symbol?

thx

(gdb) set filename-display absolute 
(gdb) info line global_options
Line number 4677 is out of range for "/quad/home/jkratoch/redhat/gcc5-build/gcc/options.h".
No line number information available for address 0x6d6020 <global_options>
(gdb) info line gcc_options
Line number 13 is out of range for "/quad/home/jkratoch/redhat/gcc5-build/gcc/options.h".
