>Description:
The file src/os/unix/os.h defines DLSYM_NEEDS_UNDERSCORE when __NetBSD__ is defined,
but the symbols do not need an underscore prepended under NetBSD/pmax 1.3.2.
>How-To-Repeat:
Compile Apache with DSO support on a NetBSD/pmax machine, then try to run it.  On a
typical installation, you'll get an error message that the server can't find symbol
_env_module in file libexec/mod_env.so.
>Fix:
Add a check for underscores to the configure script.  AFAIK, this is likely to change
in the future for all NetBSD platforms, so keeping up with #define statements is likely
to be impractical.
I can get Apache to work correctly with DSO support by hand-editing out the #define
DLSYM_NEEDS_UNDERSCORE line.

 A fix for the user's problem comes from one of the Apache patches in the
 NetBSD "pkgsrc" system:

 This solution may also be needed for FreeBSD ELF (3.0), and OpenBSD ELF; in
 that case, the expression could/should be:
 
 #if (defined(__FreeBSD__) || defined(__OpenBSD__) || defined(__NetBSD__)) \
 	&& !defined(__ELF__)
