Fix Description: Changed so that only *.c files are run through the tracing program. This is so the fortran stuff won't return spurious warnings. Platforms tested: Linux

## We keep a list of dependencies in `.depend' for each of the source
|
|
## files on which it depends. When one of the source files is modified
|
|
## we remove its record from .depend and regenerate its dependencies,
|
|
## tacking them onto the end of .depend. By including the .depend file
|
|
## into the makefile, we're telling make that the makefile depends on
|
|
## the dependency list in the .depend file.
|
|
##
|
|
## This is as fast as the `.d' method described in the GNU make manual
|
|
## for automatic dependencies, but has the added advantage that all
|
|
## dependencies are stored in one place. The advantage over the
|
|
## `makedepend' program is that only those files that are out of date
|
|
## have dependency information rebuilt, and the Makefile is not
|
|
## modified.
|
|
##
|
|
## This is also where tracing information is updated. The $(TRACE)
|
|
## program is run on each source file to make sure that the H5TRACE()
|
|
## macros are up to date. If they are then the file is not modified,
|
|
## otherwise the file is changed and a backup is saved by appending a
|
|
## tilde to the file name.
