Hi,
The problem is: glibc defines loff_t in sys/types.h, not fcntl.h (where musl
defines it). I falsely assumed that the newly committed AC_CHECK_TYPES
invocation would include fcntl.h *in addition to* AC_INCLUDES_DEFAULT.
However, as it turns out specifying includes for AC_CHECK_TYPES overwrites the
default instead of appending to it.
The patch below should fix this by appending to AC_INCLUDES_DEFAULT explicitly.
Alternatively, we could try to add fcntl.h to AC_INCLUDES_DEFAULT, though my
autotools knowledge is severely limited and hence I am not sure how this would
be achieved.

Hi,
the patch restores bootstrap for me on x86_64-suse-linux.
Franz.
