  14.  
  15. This bug report sent to both bug-gcc and bug-gdb.
  16.  
  17. There appears to be a bug in either the way fix-includes for gcc 2.2.2
  18. works or the way the gdb-4.6 source expects it to act.
  19.  
  20. Included is the tail of a compile under gcc-2.2.2 w/o any patches,
  21. fix-includes have been made, using CC=cc, which is to say:
  22.  
  23.     #!/bin/sh
  24.     /usr/local/bin/gcc -traditional -fwritable-strings -fno-defer-pop $*
  25.  
  26. using the gmake command:
  27.  
  28.     gmake CFLAGS="-DGCC_MANGLE_BUG" all-gdb
  29.  
  30. from a Makefile configured via:
  31.  
  32.     ./configure m68k-hp-bsd
  33.  
  34. The -DGCC-MANGLE_BUG is as per instructions in the gdb-4.6-gcc.patch.Z file.
  35.  
  36. I switched to CC=gcc, and it worked.
  37.  
  38. Looking at gdb-4.6/gdb/infcmd.c:879 did reveal the disturbing:
  39.  
  40.     const char * const reg_names[] = REGISTER_NAMES;
  41.  
  42. Anyhow, here's the tail:
