[Rd] configure, config.site and TCLTK_CPPFLAGS

[Laurent Gautier]

Hi,

I am trying to configure R-1.8.0-patched (fresh rsync) for machines
with the tcltk files in unorthodox locations. I specified
a TCLTK_CPPFLAGS='/usr/freeware/include/' in the file config.site
but it seems that a '# no special path needed' is added when running
configure, causing trouble (See the excerpt from config.site below).
This was working with R-1.7.1. I am not an autoconf/configure
expert, so any hint is welcome. 

Thanks,

L.
