May I suggest a code generating macro instead:
#define PRINT_FS(pref, fs, suf) \
case pref##fs##suf: \
printf (#fs "\n"); \
break;
And in the code:
switch (statfsbuf.f_type) {
#ifdef FSTYPE_EXT2
PRINT_FS(FSTYPE_,EXT2,)
#endif
#ifdef EXT2_SUPER_MAGIC
PRINT_FS(,EXT2,SUER_MAGIC);
#endif
...
}
Simpler cleaner and no need to maintain a separate list of supported
filesystems.
