i'm thinking of using protoize to help convert a large (1+ mega-line)
body of code over to ansi.  prototyping is the first obvious and
most useful step.  protoize seems to do a great job, but produces
some warnings that have me confused:

protoize: converting file `srf.c'
srf.c: 597: warning: `else' excluded by preprocessing
protoize: function definition not converted
srf.c: 620: warning: `else' excluded by preprocessing
protoize: function definition not converted

i've included that area of code below.  i realize that the line numbers might
be off a bit, but there is no preprocessing around that area.  any idea what
might be going on?  this is happening in multiple files and always is
confused by 'else'.  any help would be appreciated.

srf.c:
592   /* left-justify the keyword */
593      if (iCol == 0)
594          (void) fprintf (fpSrfOut, "#%% %-*s", (widthOfCol[iCol] - 3), name);
595      else
596          (void) fprintf (fpSrfOut, " %-*s", widthOfCol[iCol], name);
597      return;
598  }
