Here is some further analysis:
lftp’s configure script checks for a working stdint.h and that test
fails on kfreebsd-i386 (tested on fischer.debian.org). The test contains
these lines at the top of the file:
#define _GL_JUST_INCLUDE_SYSTEM_STDINT_H 1
#include <stdint.h>
#if !(defined WCHAR_MIN && defined WCHAR_MAX)
#error "WCHAR_MIN, WCHAR_MAX not defined in <stdint.h>"
#endif
However, libc0.1-dev:kfreebsd-i386’s /usr/include/stdint.h defines
WCHAR_MIN and others within a block that is guarded by:
/* The ISO C99 standard specifies that in C++ implementations these
macros should only be defined if explicitly requested. */
#if !defined __cplusplus || defined __STDC_LIMIT_MACROS
Looking at the current version of the corresponding m4 file, it seems
like this was already fixed in autotools:
http://codesearch.debian.net/show?file=m4_1.4.16-3%2Fm4%2Fstdint.m4&line=70&numfiles=185#L70
I therefore think that this bug can be fixed by "simply" rebuilding
lftp’s configure. However, I have no clue on what the best way to do
this is, so I’ll leave that up to somebody else.
