Remove more obsolete autoconf macro's 

Autoconf 2.71 warns about obsolete macro's on running ./autogen.sh.

AC_PROG_CC_STDC is replaced by AC_PROG_CC as recommended by autoupdate

AC_HEADER_STDC has been removed. Autoupdate recommended the following:
> The preprocessor macro `STDC_HEADERS' is obsolete. Except in unusual
> embedded environments, you can safely include all ISO C90 headers
> unconditionally.
