I have had a few errors in building web2c which are bothersome at best, and I am worried about using the compiled programs. Following are excerpts from the `make': ********** gcc -g -O -I.. -c dvitype.c dvitype.c: In function opendvifile: dvitype.c:214: warning: argument passing between incompatible pointer types dvitype.c:221: warning: argument passing between incompatible pointer types dvitype.c:221: warning: argument passing between incompatible pointer types dvitype.c: In function opentfmfile: dvitype.c:243: warning: argument passing between incompatible pointer types dvitype.c:243: warning: argument passing between incompatible pointer types gcc -g -O -I.. -c pooltype.c pooltype.c: In function main_body: pooltype.c:171: warning: argument passing between incompatible pointer types pooltype.c:172: warning: argument passing between incompatible pointer types pooltype.c:172: warning: argument passing between incompatible pointer types gcc -g -O -Dlink=link_array -I.. -c gftodvi.c gftodvi.c: In function opengffile: gftodvi.c:355: warning: assignment of pointer from integer lacks a cast gftodvi.c:355: warning: assignment of pointer from integer lacks a cast gftodvi.c: In function opentfmfile: gftodvi.c:387: warning: assignment of pointer from integer lacks a cast gftodvi.c:387: warning: assignment of pointer from integer lacks a cast gftodvi.c: In function opendvifile: gftodvi.c:401: warning: assignment of pointer from integer lacks a cast gftodvi.c:401: warning: assignment of pointer from integer lacks a cast gcc -g -O -Dlink=link_array -I.. -c gftopk.c gftopk.c: In function opengffile: gftopk.c:205: warning: assignment of pointer from integer lacks a cast gftopk.c:205: warning: assignment of pointer from integer lacks a cast gftopk.c: In function openpkfile: gftopk.c:280: warning: assignment of pointer from integer lacks a cast gftopk.c:280: warning: assignment of pointer from integer lacks a cast gcc -g -O -Dlink=link_array -I.. -c mft.c mft.c: In function initialize: mft.c:425: warning: assignment of pointer from integer lacks a cast mft.c:425: warning: assignment of pointer from integer lacks a cast mft.c: In function openinput: mft.c:493: warning: assignment of pointer from integer lacks a cast mft.c:493: warning: assignment of pointer from integer lacks a cast mft.c:494: warning: assignment of pointer from integer lacks a cast mft.c:494: warning: assignment of pointer from integer lacks a cast mft.c:505: warning: assignment of pointer from integer lacks a cast mft.c:505: warning: assignment of pointer from integer lacks a cast gcc -g -O -I.. -c bibtex.c bibtex.c: In function predefcertainstrings: bibtex.c:2136: warning: argument passing of pointer from integer lacks a cast bibtex.c:2137: warning: argument passing of pointer from integer lacks a cast ********** The bibtex warnings were by far the most severe: there were about 143 of the `assignment of pointer from integer lacks a cast' warnings, along with a few `argument passing between incompatible pointer types', just for kicks :-) Following is the site.h file which I modified for our use: I'm building this on a SPARCstation 1 (running SunOS 4.0.3c) with gcc. ********** /* Master configuration file for WEB to C.
