	Allow users of gprof to get per run output files (using the pid)

Simplify the calculation of s_scale by rewriting the FP expression to

2010-07-01T00:48:00+00:00

use uintmax_t instead of float and thereby eliminating the need for
a non-FP version.

Tested on: amd64, ia64 & powerpc (book-E)

On powerpc, calculate s_scale using the non-FP version previously

2010-06-30T01:40:25+00:00

specific to hp300. Since FreeBSD does not support hp300, hp300 has
been removed from the condition altogether.

The FP version broke profiling on powerpc due to invalid results.
Casting to double instead of float resolved the issue, but with
Book-E not having a FP unit, the non-FP version looked preferrable.
Note that even on AIM hardware the FP version yielded an invalid
value for s_scale, so the problem is most likely with the compiler
or with the expression itself.

Fix many "function declaration isn't a prototype" warnings in libc.

I've only fixed code that seems to be written by `us'. There are still
many warnings like this present in resolv/, rpc/, stdtime/ and yp/.

Remove .mcount from gmon's Symbol map and add it to the appropriate

arch.  It can be named differently depending on the arch (.mcount,
_mcount).

Use C comments since we now preprocess these files with CPP.

Per Regents of the University of Calfornia letter, remove advertising

clause.

# If I've done so improperly on a file, please let me know.

Backed out rev.1.10 (a special case for amd64). The amd64 mcount code

2006-10-28T13:34:35+00:00

never needed any frame pointers for itself.

Add each directory's symbol map file to SYM_MAPS.
