Subject: Problem cross compiling Ruby

Hello,

When I cross compile ruby 1.6.7 on i386 for arm, I encountered the
following problem:

When using
  --prefix=/usr
the Makefile places -I/usr/include in the CPPFLAGS. For the cross
compiler, this is the wrong directory, but it tries to take various
header files from there, before it looks in its own
directories. Arm-linux-gcc breaks down on unknown assembler.

For local install (non cross compiling) this include seems a useful
option, since prefix defaults to /usr/local, the place where extra
packages are put in some (older) schemes.

For cross compiling, the prefix is good, but I can not think of a good
default for the include; It certainly is not /usr/local/include.
Perhaps we should drop it altogether?

Bye,
Kero.

PS: work-around: --includedir=.
