rexx install - build failure due to -xchar=unsigned

[Dale Miller]

Trying to install port rexx (3.3) on Leapord on a G5, the build fails.  
All compile steps bomb with the following message(s)
	powerpc-apple-darwin9-gcc-4.0.1: language char=unsigned not recognized
I traced this to a line in the generated Makefile:
	CEXTRA = -DREGINA_SHARE_DIRECTORY=\"$(sharedir)\" -xchar=unsigned
I tried the install with and without the only listed variant  
(universal) with no success.
I was able to capture the makefile, and modify it by removing the  
offending option from the CEXTRA line. I was able to run the make  
manually, but of course attempting to run the install again results in  
regenerating the bad makefile, with the same errors.
Is this a bug or a short between the headset and the stick on my part?
