re PR other/5620 (GCC -save-temps foo.c fails to build foo.o)
PR 5620
* gcc.c (struct stat input_stat): Don't define if
HOST_LACKS_INODE_NUMBERS
(do_spec_1): If HOST_LACKS_INODE_NUMBERS, use lrealpath rather
than stat to determine if temp file is same as input file.
* doc/hostconfig.texi: Document HOST_LACKS_INODE_NUMBERS.
* config/i386/xm-mingw32.h: Define HOST_LACKS_INODE_NUMBERS
