On MacOS X 10.3 / PowerPC, variables that are implicitly zero-initialized
can lead to link errors:
$ gcc -g -O2 -o test-mbsnrtowcs test-mbsnrtowcs.o ../gllib/libgnu.a
ld: Undefined symbols:
__gl_mbsrtowcs_state
This fixes it:
2009-01-25 Bruno Haible <br...@clisp.org>
Avoid link errors on MacOS X 10.3.
* lib/mbsrtowcs-state.c (_gl_mbsrtowcs_state): Add initializer.
* lib/wcsrtombs-state.c (_gl_wcsrtombs_state): Likewise.
