So far, I've been pretty diligent about making my applications
cross-platform compatible -- in this case, these are physics calculations that
run only under Linux (but could be made to run under Windows).
Are we sure about add_fd in Windows? Windows supports _popen() which is the
same as Linux popen(); I use these directives:
#ifdef WIN32
#include <Windows.h>
#include <Commdlg.h>
#include <direct.h>
#define popen _popen
#define pclose _pclose
#define fl_message(a) MessageBox(0, a, "Message", 0)
inline char* dirname(char *a) {int i; for(i=strlen(a); i>0; i--) {if
(a[i] == '\\') break;} a[i]=NULL; return a;}
#define getcwd _getcwd
#define rint(a) ((float) ((int) (a) + .5))
#else
..
