This specific instance it quite weird:

 o First, why is the file called fits.E?

 o Second, the file contains references to lib/gcc-lib/sparc-sun-solaris2/
   instead of ...solaris2.8 which the reporter is using.

 o Third, when I rename it to fits.ii and compile it with current CVS,
   on sparc-sun-solaris2.8 I get parse errors:

  When I compile with 3.0.3-snapshot, I get:

  ../../../src/ImageMagick-5.3.8/coders/fits.c:482: confused by earlier
  errors, bailing out

Given the error message, it seems this was an instance of ICE on invalid
code, and the report can be closed (for mainline and apparently also
branch).

HTH,
