Actually, I hate to burst your bubble, but I think that this is not the
reason. Remember that I fixed the missing OBJDUMP defines, and Chuck
included those patches in 2.2.2-2 and pushed them upstream. AFAICS, the
problem is, once again, gettext.
Old versions of lib-link.m4 (pre-0.12) define sys_lib_search_path_spec
from config.rpath output, and for Cygwin sets it to "/lib /usr/lib
/usr/local/lib". (Which also happens to be the default value in libtool,
and was a red herring causing me to look into libtool itself as the
problem instead of something else.) But libtool-2.2 uses that variable
to know where to look for libraries by default, and sets it on Cygwin to
"/usr/lib /lib/w32api /lib /usr/local/lib". However, since
AM_GNU_GETTEXT (or AM_ICONV) is invariably called *after*
AC_PROG_LIBTOOL/LT_INIT, the correct value is clobbered, and suddenly
libtool can't find a library that the linker can.
This explains why:
1) this happened only sporadically (not every package uses
AM_GNU_GETTEXT or AM_ICONV);
2) there was a difference in behaviour between libtool generated by
config.lt (with LT_OUTPUT) and the libtool generated by config.status at
the end of configure (only the latter was poisoned).
Now, I mentioned before that there were other such conflicts with this
macro; they were fixed in gettext, but only before 0.17. Since
autopoint will pull in the exact version of the macros specified in
AM_GNU_GETTEXT_VERSION, not only must the gettext package be updated to
0.17, but packages need to be forced to use the newest version as well.
AFAICS the possible solutions are:
1) fix each package's call to AM_GNU_GETTEXT_VERSION to 0.17;
2) change autopoint to treat the value as a minimum instead of an absolute.
If the latter is possible, it would make things a lot easier than
patching configure.ac every single time (although perhaps I could
automate that with cygport).
