* config/i386/xm-djgpp.h (HAVE_DOS_BASED_FILE_SYSTEM): Renamed
from HAVE_DOS_BASED_FILESYSTEM.
* gcc.c (find_a_file): Use HAVE_DOS_BASED_FILE_SYSTEM, not
HAVE_DOS_BASED_FILESYSTEM.
(main): Likewise.
(split_directories): Only special-case DOS file names if
HAVE_DOS_BASED_FILE_SYSTEM is defined. Use IS_DIR_SEPARATOR
instead of explicit tests. Conditionalize on !VMS.
(make_relative_prefix): Use IS_DIR_SEPARATOR instead of explicit
tests. Conditionalize on !VMS.
(process_command): Only use make_relative_prefix if !VMS.
(free_split_directories): Conditionalize on !VMS.
(DIR_UP): Conditionalize on !VMS.

* gcc.c (STANDARD_BINDIR_PREFIX): Provide default.
Fri Feb 5 14:22:01 1999 Mumit Khan <khan@xraylith.wisc.edu>
* gcc.c (make_relative_prefix): Handle the HAVE_EXECUTABLE_SUFFIX
case.
Mon Nov 8 14:16:57 1999 Michael Meissner <meissner@cygnus.com>
* invoke.texi (Environment Variables): Document relative path
lookup.
* gcc.c (DIR_UP): If not defined, define as "..".
(standard_bindir_prefix): New static, holds target location to
install binaries.
(split_directories): New function to split a filename into
component directories.
(free_split_directories): New function, release memory allocated
by split_directories.
(make_relative_prefix): New function, make a relative pathname if
the compiler is not in the expected location.
(process_command): If GCC_EXEC_PREFIX was not specified, see if we
can figure out an appropriate prefix from argv[0].
* Makefile.in (DRIVER_DEFINES): Use unlibsubdir in definition of
STANDARD_STARTFILE_PREFIX and TOOLDIR_BASE_PREFIX. Define
STANDARD_BINDIR_PREFIX.
