I've picked an example: /usr/lib/libbsnmp.a It contains the string "/usr/home/erik/freebsd/head1/src/lib/libbsnmp/libbsnmp/../../../contrib/bsnmp/lib/asn1.c" in the section .rodata.str1.8 of the archive member asn1.o. asn1.o was created during buildworld with this command: cc -O2 -pipe -DSTRIP_FBSDID -I/usr/home/erik/freebsd/head1/src/lib/libbsnmp/libbsnmp/../../../contrib/bsnmp/lib -DHAVE_ERR_H -DHAVE_GETADDRINFO -DHAVE_STRLCPY -DHAVE_STDINT_H -DHAVE_INTTYPES_H -DQUADFMT='"llu"' -DQUADXFMT='"llx"' -std=gnu99 -fstack-protector -Wsystem-headers -Wall -Wno-format-y2k -W -Wno-unused-parameter -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Wreturn-type -Wcast-qual -Wwrite-strings -Wswitch -Wshadow -Wunused-parameter -Wcast-align -Wchar-subscripts -Winline -Wnested-externs -Wredundant-decls -Wold-style-definition -Wno-pointer-sign -c /usr/home/erik/freebsd/head1/src/lib/libbsnmp/libbsnmp/../../../contrib/bsnmp/lib/asn1.c I don't see __FILE__ anywhere in asn1.c or in dependent files.
