  3. <para><userinput>CPPFLAGS=-Dre_max_failures=re_max_failures2:</userinput> The
  4. CPPFLAGS variable is a variable that's read by the cpp program (C
  5. PreProcessor). The value of this variable tells the preprocessor to
  6. replace every instance of re_max_failures it finds by re_max_failures2
  7. before handing the source file to the compiler itself for compilation. This
  8. package has problems linking statically on systems that run an older
  9. Glibc version and this construction fixes that problem.</para>
  10. <para><userinput>PR_PROGRAM=/usr/bin/pr:</userinput> When 'diff' is called
  11. with the '-l' flag, it tries to find 'pr' at the location specified with the
  12. PR_PROGRAM variable. By default, this variable points to '/bin/pr', but since
  13. we install 'pr' in /usr/bin, we need to change this.</para>
