Write.available() is different on Mac and PC

I installed version 1.0.1 of the IDE today.

Wire.available() returns different values depending on the platform.

in master_receiver on the PC (with slave_sender running on the Mac)
while(wCount = Wire.available()) // slave may send less than requested
Serial.print(wCount,DEC); // always returns a value of 1

in slave_receiver on the Mac (with master_sender running on the PC)
while(wCount = Wire.available()) // slave may send less than requested
Serial.print(wCount,DEC); // always returns the number of bytes remaining in the message

Could someone verify this and then report it as a bug?

Have you tried swapping over, so master_receiver is on the Mac?

Well, I thought that I tested that but ...

in slave_receiver on the PC (with master_sender running on the Mac)
while(wCount = Wire.available()) // slave may send less than requested
Serial.print(wCount,DEC); // always returns the number of bytes remaining in the message

in master_reader on the Mac(with slave_sender running on the PC)
while(wCount = Wire.available()) // slave may send less than requested
Serial.print(wCount,DEC); // returns the number of bytes remaining in the message

So I tested the failed example again and got this ...

in master_receiver on the PC (with slave_sender running on the Mac)
while(wCount = Wire.available()) // slave may send less than requested
Serial.print(wCount,DEC); // returns the number of bytes remaining in the message

I apparently made a mistake. It is working now. I may have mis-spelled a variable name.
Thanks for checking this.
