To help work around this problem I've generated a test release; please
give it a try.


I have made no announcement yet, and may not bother, since the GLR
parser has changed quite a bit and I expect some shakedown problems.
For example, as I write this message I see that the Simple GLR
calculator is failing on 64-bit Solaris 8 (Sun Forte Developer 7 C++
5.4) as follows:

Simple GLR Calculator.

 66: calc.at:581       FAILED near `calc.at:581'
 67: calc.at:583       FAILED near `calc.at:583'
 68: calc.at:584       ok
 69: calc.at:585       FAILED near `calc.at:585'
 70: calc.at:586       FAILED near `calc.at:586'
 71: calc.at:587       FAILED near `calc.at:587'
 72: calc.at:588       FAILED near `calc.at:588'
 73: calc.at:590       ok
 74: calc.at:591       ok
 75: calc.at:593       ok
 76: calc.at:595       FAILED near `calc.at:595'
 77: calc.at:596       ok
 78: calc.at:598       ok
 79: calc.at:600       ok

I'll take a look at this when I have more time; with luck there will
be a 1.875c soon.
