Re: standards/51044 (NetBSD cdefs.h defines __func__ incompatibly with C99)

No, I am complaining that the NetBSD headers trample on __func__ provided
by compilers, and redefine it as __PRETTY_FUNCTION__ instead of the
compiler's definition, based on a __GNUC_PREREQ__ macro, and that
results in different behavior when compiling with clang on NetBSD only
(Linux, illumos headers do not trample on __func__). gcc happens to
define the non-standard __PRETTY_FUNCTION__ as equivalent to
__FUNCTION__, whereas clang does not. As __PRETTY_FUNCTION__
is non-standard, and differs among gcc-compatible compilers it should
probably not be used to redefine __func__, nor is it useful in assertion
messages, for the same reasons of incompatibility.
