* autogen.sh: Add "-I macros" to the aclocal flags.
* mc-aclocal.m4: Renamed fp_PROG_CC_STDC to MC_HPUX_PROG_CC_STDC
so that aclocal will not complain about an obsolete macro.
* configure.in: Use MC_HPUX_PROG_CC_STDC
* ChangeLog: There was no ChangeLog here, so I added one.
* mc-local.m4 (AC_STRUCT_LINGER): Moved into macros/linger.m4.
* autogen.sh: Include linger.m4 in aclocal.m4.
* Makefile.in (GNOME_M4_FILES): Include linger.m4.
