If an expression matches multiple files than the results will be

sorted.@footnote{Some older versions of GNU @code{make} did not sort the

results of wildcard expansion.} However multiple expressions will not be

globally sorted. For example, @file{*.c *.h} will list all the files whose
|

names end in @samp{.c}, sorted, followed by all the files whose names end in
|

|
@samp{.h}, sorted.

As with wildcard expansion in rules, the results of the @code{wildcard}
|
||||||
|
function are sorted. But again, each individual expression is sorted
|
||||||
|
separately, so @samp{$(wildcard *.c *.h)} will expand to all files matching
|
||||||
|
@samp{.c}, sorted, followed by all files matching @samp{.h}, sorted.
