    Fixes a bug in the microblaze assembler where it would not complain about constants larger than 32-bits.
    
    	PR gas/18189
    	* config/tc-microblaze.c (parse_imm): Use offsetT as the type for
    	min and max parameters.

    Second fix for microblaze gas port's ability to parse constants.
    
    	PR gas/18189
    	* config/tc-microblaze.c (parse_imm): Use offsetT as the type for
    	min and max parameters.  Sign extend values before testing.
