- Howdy.
-
- I have finished porting gcc-2.3.2 to the NCR-3350, and used it to compile
- X11R5p21 and libg++-2.3. This report concerns the float.h include file.
-
- Cheers,

- Analysis: <float.h> uses a lower case "e" in the indicated definitions,
- where <syslimits.h> uses an upper case "E".
-
- Solution: Modify <float.h> to use upper case "E".
