1.18.1 breaks fuse (not macfuse) support on macOS

[Aleksanaa]

The commit 3293dc9 breaks building against fuse (https://github.com/libfuse/libfuse) on macOS, throwing

bindfs.c:1794:19: error: incompatible function pointer types initializing 'int (*)(const char *, const char *, const char *, size_t, int, uint32_t)' (aka 'int (*)(const char *, const char *, const char *, unsigned long, int, unsigned int)') with an expression of type 'int (const char *, const char *, const char *, size_t, int)' (aka 'int (const char *, const char *, const char *, unsigned long, int)') [-Wincompatible-function-pointer-types]

Reverting that commit resolves the issue.
