Subject: [PATCH] cpp-if1.c: New test - torture test of preprocessor's number
 conversion in #if directives.

* cpp-if1.c: New test - torture test of preprocessor's number conversion
  in #if directives.
* cpp-if2.c: New test - torture test of preprocessor's character constant
  conversion in #if directives.
Both these tests are entirely my own invention.
