# Starting with 0.21, gettext cannot build against uClibc-NG: gettext
# checks if it needs to use fopen wrapper (using gnulib) and newer versions
# of gnulib also check if fopen provided by the system supports 'e' and 'x'
# modes. In cross-compile environment, gnulib falls back to assuming fopen
# does not support these modes unless the target tuple is glibc or musl
# (rightly so, since these fopen modes are optional in uClibc-NG).
# Unfortunately, the fopen() wrapper does not compile against uClibc-NG's
# stdio.h then because it includes <stdio.h> after defining __need_FILE macro.
# It looks like two bugs, one in each of uClibc-ng and gnulib:
# - uClibc-ng does not include its internal headers with the definitions for the
# __BEGIN_NAMESPACE_STD/__END_NAMESPACE_STD macros, which therefore escape
# unsubstituted into the including code.
# - gnulib shouldn't expect the fopen() prototype if it only asked for FILE
# structure definition by defining the __need_FILE macro.
# Until the maintainers sort this out, disallow newer gettext versions if
# linking against uClibc-NG.
