If you have a fully ANSI-compliant set of #include files and
C libraries, then compiling nrtodp should be simple. The following line
should be sufficient:

	cc -DLIBRARY_DIR=\"your library dir here\" -O -s -o nrtodp nrtodp.c

	Type the \" exactly as indicated, but replace the phrase 'your
library dir here' with the directory in which you will install
nrtodp.dat. Depending on your compiler, the option -DANSI might also be
required in the above. However, not all environments have ANSI string
functions. The ones most likely to be a problem are strchr, strrchr and
strstr. In some cases, strchr and strrchr are called, respectively,
index and rindex. So if you receive an error message about "_strchr" and
"_strrchr" being undefined, try the following:

	cc -Dstrchr=index -Dstrrchr=rindex -DLIBRARY_DIR=\"your library dir here\" -O -s -o nrtodp nrtodp.c

	It is possible that the function strstr is not present in any
form. For convenience, files implementing strchr, strrchr, and strstr are
present in this directory. These sources are not part of Numerical
Recipes, but are from the second Berkeley networking distribution.
Please note the conditions on their use and redistribution. At this
point, compiling advice becomes heavily system-dependent, so we refer
you to your local experts.
