#2 Patch2 to fix bugs of V.2.6.1

[Kiyoshi Matsui]

mcpp V.2.6 and V.2.6.1 have some bugs other than
the ones fixed by the previous mcpp-2.6.1-patch1:

1. -Wtraditional or some other such warning
options gets an error.

2. Timing of macro expansion in #include line is
sometimes wrong.

Please apply this patch, especially if you process
some GNU sources. Note that this mcpp-2.6.1-
patch2 should be applied after applying the mcpp-2.
6.1-patch1.
