Update.
1999-05-16 Wolfram Gloger <wmglo@dent.med.uni-muenchen.de> * malloc/malloc.c: Cleanup to bring in line with released stand-alone version `ptmalloc'. Update some comments. (internal_function): Move fallback definition so that the source compiles outside of libc, and use it in more places. (malloc_atfork): Fix when malloc_check is in use. 1999-05-16 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * stdlib/tst-strtod.c: Fix typo. 1999-05-16 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * elf/dl-close.c (_dl_close): Add cast to avoid warning about const incorrectness.
