How to install libm_p.a?
Not that this is particularly helpful, but profiled libs (afaik) are in
/usr/lib/profile and it would be /usr/lib/profile/libm.a in this case.
I tried it and set a link to the library.

$ ls -l /usr/lib/libm_p.a
lrwxr-xr-x  1 root  wheel  23 May 27 23:48 /usr/lib/libm_p.a@ ->  /usr/lib/profile/libm.a
Compile now ok, but weird result, argv=0x0 ?!
Damian,

it's because of the optimization, see 
http://leaf.dragonflybsd.org/mailarchive/kernel/2010-04/msg00023.html.

Maybe Venkatesh found out more in the meantime and can chime in.

One would have to find out how to prevent optimization from setting 
argc/argv to 0. In the meantime you could set CFLAGS to "-O0 -pipe" (the 
default is "-O -pipe") and recompile/-install libc.
