devel/m4 build failure for current amd64

[Jimmy Johansson <jimmy+netbsd%Update.UU.SE@localhost>]

Hi,

devel/m4 fails to build for me on NetBSD 5.99.62 amd64. It fails for
both head of pkgsrc and pkgsrc-2011Q4 and in the exactly same way for
both branches.

It fails like this:

fflush.c: In function 'update_fpos_cache':
fflush.c:108:16: error: incompatible types when assigning to type
'__off_t' from type 'fpos_t'
*** Error code 1

Stop.

These 2 patches makes m4 build:

These are not fixes though, and the diffs should not be taken as such, just
a change I made to make it build and to highlight the lines that makes it
not build for me, so somebody with knowledge can look at it.

Regards,

Jimmy
