1998-03-15 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * posix/wordexp-test.c: Add more tests. (testit): Fix logic. * posix/wordexp.c (exec_comm): In the child, redirect stderr to /dev/null instead of closing it, close pipe. Always chop off all trailing newlines. Kill and reap child before returning error. (w_addword, parse_glob): Fix memory leak. (wordexp): Fix dangling pointer problem. 1998-03-16 Ulrich Drepper <drepper@cygnus.com> * elf/dl-close.c (_dl_close): Correct and simplify unmapping. * posix/wordexp-test.c (main): Fix little thinkos and typos. * catgets/Makefile (CPPFLAGS): Change NLSPATH to also examine directory index by only the language.
