(exchange): Cast return value of malloc(). * hashtab.c (htab_size): Define as both macro and non-inline function. (htab_elements): Likewise. * getpwd.c (getpwd): Use XNEWVEC. (htab_create_alloc_ex): Use C90 prototype-style. * lrealpath.c (lrealpath): Appropriately cast return value of malloc(). * make-relative-prefix.c (save_string): Likewise. * make-temp-file.c (try_dir): Rename from "try". Adjust use in the file. (choose_tmpdir): Use XNEWVEC. * mkstemps.c (mkstemps): Rename parameter "template" to "pattern". * pex-common.c (pex_init_common): Use XNEW. (pex_add_remove): Use XRESIZEVEC.
