If you build your program with -ggdb that'll include extra debugging information gdb can use. I don't know any way to make this debugging information available to the program itself at runtime -- would you want a program that could only be built with gdb, and only built for debugging? Talk about unportable.
Even if you end up using gdb for something else I don't see the harm in using the __FILE__, etc. C macros to do what they were designed to do.

gdb-add-index
GDB-ADD-INDEX(1) GNU Development Tools GDB-ADD-INDEX(1)
NAME
gdb-add-index - Add index files to speed up GDB
SYNOPSIS
gdb-add-index filename
DESCRIPTION
When GDB finds a symbol file, it scans the symbols in the file in order to construct an internal symbol table. This lets most GDB
operations work quickly--at the cost of a delay early on. For large programs, this delay can be quite lengthy, so GDB provides a way to
build an index, which speeds up startup.
To determine whether a file contains such an index, use the command readelf -S filename: the index is stored in a section named
".gdb_index". Note that the index is never generated for files that do not contain DWARF debug information (sections named ".debug_*").
See more in the GDB manual in node "Index Files" -- shell command "info -f gdb -n 'Index Files'".
OPTIONS
SEE ALSO
The full documentation for GDB is maintained as a Texinfo manual. If the "info" and "gdb" programs and GDB's Texinfo documentation are
properly installed at your site, the command
info gdb
should give you access to the complete manual.
