gcc compile error

when compiling gcc 4.8 for cross linux from scratch it throws this error:

 gcc-4.8.2/gcc/doc/gcc.texi:88: warning: @tex should only
  appear at the beginning of a line gcc-4.8.2/gcc/doc/gcc.texi:208: no matching
  `@end tex' gcc-4.8.2/gcc/doc/gcc.texi:208: no matching `@end multitable'
  gcc-4.8.2/gcc/doc/gcc.texi:208: no matching `@end titlepage' 

and can be fixed using this patch.

Later when compiling gcc for the 2nd time it throws another error:

 In file included from ../../gcc-4.8.3/gcc/cp/except.c:1008:
  cfns.gperf:101:1: error: 'const char* libc_name_p(const char*, unsigned int)'
  redeclared inline with 'gnu_inline' attribute cfns.gperf:26:14: note: 'const
  char* libc_name_p(const char*, unsigned int)' previously declared here
  cfns.gperf:26:14: warning: inline function 'const char* libc_name_p(const

  Error 2 make[1]: Leaving directory '/media/clfs/sources/gcc-build' make: ***
  [Makefile:858: all] Error 2 

and that one can be fixed by applying this patch.
