Indeed, it is a better solution than editing the C code :).

These days we have been testing the last Erlang release (R9C-1) and,
unfortunately, the Erlang ODBC support doesn't compile yet in an i686
linux machine. Nevertheless, the solution is pretty simple and we hope it
to be useful for other users:

	* Be sure that the LC_ALL enviroment variable is set to C (as
	  during the architecture detection, the output of some
	  shell comands are used and english output is expected)

	* Set the undocumented ERLANG_COMMERCIAL_BUILD enviroment variable
	  with any value like "ACME Erlang Build" :)

	* Run the configure command

		./configure ... --enable-odbc

	* In the <otp-src-erlang-home>/lib/Makefile and the
	  files look for the conditional statements involving "solaris" and
	  comment them out (note that we are working with an
	  i686-pc-linux-gnu box)

	* Finally, compile and install.

Enjoy it
