C compilers do this in conjunction with external tools.

On VMS the CC command qualifier /MMS_DEPENDENCIES creates (in addition
to any output specified by other qualifiers) an MMS description file
suitable for describing the conditions under which this file should
be compiled again (based on modification dates of included files as
well as the mail file).

C compilers are likely not so equal to each other as Ada compilers
in this regard, but I think that at decision-points regarding ease
of use, comparisons will be made between a particular Ada compiler
and a particular C compiler, rather than the field in general.
