Preprocessed source from building rw_bitmaps.c with gcc-13
Since gcc-13, there is a regression in the SH backend which results in an
internal compiler error with the error message "Illegal instruction":

gcc-12 works fine:
root@tirpitz:..lib/ext2fs> gcc-12 -I. -I../../lib -I../../../../lib -Wdate-time
-D_FORTIFY_SOURCE=2 -g -O2 -ffile-prefix-map=$(pwd)=.

-Werror=format-security -pthread -DHAVE_CONFIG_H -c
../../../../lib/ext2fs/rw_bitmaps.c -o rw_bitmaps.o
