It was historically declared to be ! double in math.h. More contemporary systems declare it only in stdlib.h. ! Xephem includes stdlib.h if __STDC__ is defined, else it assumes atof() ! is declared in math.h. This should work pretty well but if you get ! crazy numbers from xephem check the files that use atof and figure out a ! way to get it declared to return a double. Atof() is called in compiler.c, ! db.c, formats.c, mainmenu.c and satmenu.c. - Also, on some systems (such as SVR3.2) compile with -D_NO_PROTO and -DSYSV. - I have searched carefully through the output of running all of xephem through lint and gcc on Ultrix and SVR4 and can rationalize all the warnings so don't let these bother you. --- 35,42 ---- If not, there is also a Makefile.simple. !
