CPLUS_INCLUDE_PATH causes compilation errors on Slackware 64-bit

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Try to compile the bareminimum sketch with the shipped avr-toolchain.
2. gcc wil throw a bunch of errors.

I see:

What version of the Arduino software are you using? On what operating
system?  Which Arduino board are you using?
1.0.1 on slackware64 current and 13.37

Please provide any additional information below.
This problem seems to be caused by using non-standard functions.
They should be replaced by ANSII standards to run everywhere.

FIX: unset the CPLUS_INCLUDE_PATH environment variable.

Hmm, how does the CPLUS_INCLUDE_PATH get set?  If it's set by default on 
Slackware, maybe we need to clear it in the arduino launch script or something.

• Changed title: CPLUS_INCLUDE_PATH causes compilation errors on Slackware 64-bit
• Added labels: OpSys-Linux

I already did that for the slackbuild itself. 
(http://slackbuilds.org/repository/13.37/development/arduino/)
There is a new version pending for 1.0.1 for which this has been solved.

It can get set when using certain IDE's which drop extra configuration into the 
default profiles and it's not slackwares default setting!

You can close this bug if you like.

Okay, closing this.  Thanks for looking into it!
