Yes it is ;)

AC_CHECK_HEADERS([some.h other.h])
Will generate #define HAVE_SOME_H and #define HAVE_OTHER_H if the headers
were found. Then in your code, you can do fancy stuff with the pre-processor
based on these #defines.
Also, there is quite a couple of predefined checks for special
headers/functions that you might to check out, e.g. AC_FUNC_SELECT_ARGTYPES
