 239 The NetBSD build system requires a shell that supports modern POSIX
 240 features, as well as the "local" keyword in functions (which is a
 241 widely-implemented but non-standardised feature).
 242
 243 Please re-run this script under a suitable shell.  For example:
 244
 245         /path/to/suitable/shell $0 ...
 246
 247 The above command will usually enable build.sh to automatically set
 248 HOST_SH=/path/to/suitable/shell, but if that fails, then you may also
 249 need to explicitly set the HOST_SH environment variable, as follows:
 250
 251         HOST_SH=/path/to/suitable/shell
 252         export HOST_SH
 253         \${HOST_SH} $0 ...
 254 EOF
 255     exit 1
 256 fi
 257
 258 #
 259 # }}} End shell feature tests.

1365 # might already have an up to date version of nbmake in TOOLDIR, but we

1369 # level object directory, so $(getmakevar TOOLDIR) invoked before or
1370 # after making the top level object directory may produce different
1371 # results.

1375 #    1. build a new version of nbmake in a temporary directory;
