12.1.2 Accessing Type Information in C

Generally, C code written to link with g77 code--calling and/or being called from Fortran--should `#include <g2c.h>' to define the C versions of the Fortran types. Don't assume Fortran INTEGER types correspond to C ints, for instance; instead, declare them as integer, a type defined by `g2c.h'. `g2c.h' is installed where gcc will find it by default, assuming you use a copy of gcc compatible with g77, probably built at the same time as g77.
