This reminds me of a question that came up while I was trying to build
a sparc64 version:  Is it intended that the current GDB5 sources compile only
on GCC?  For example, in findvar.c, there is the line

  char raw_buffer[MAX_REGISTER_RAW_SIZE];

Since MAX_REGISTER_RAW_SIZE is not an integral constant expression,
this does not compile with Sun's compiler.  No doubt I simply missed
this policy discussion when it came up.  Is it no longer considered
important to allow GDB to compile with standard C compilers?
