2009-10-15malloc: handle size overflows in realloc()Mike Frysinger
The malloc() code checks the incoming size to make sure the header adjustment doesn't cause overflow in the size storage. Add the same check to realloc() to catch stupid stuff like realloc(..., -1).

2009-03-25- Add strtouq alias (to strtoul) for 64bitBernhard Reutner-Fischer
The strtouq alias was only available on 32bit, breaking compilation of stuff using strtouq on 64bit machines. At the same time use the correct return type (u_quad_t). Signed-of-by: Peter Korsgaard <jacmet@sunsite.dk>
2009-01-21*: remove __UCLIBC_CURLOCALE_DATA, __UCLIBC_CURLOCALE_DATA.xDenis Vlasenko
is always equivalent to __UCLIBC_CURLOCALE->x. remove typedef __uclibc_locale_t, it used only in a few places, it is lees confusing to use struct __uclibc_locale_struct everywhere. xlocale.h: hide __global_locale back under _LIBC, bug 53 is wrong in claiming it should be exported. Also hide under _LIBC: extern __locale_t __curlocale_var; extern __locale_t __curlocale(void); extern __locale_t __curlocale_set(__locale_t newloc); # define __UCLIBC_CURLOCALE # define __XL_NPP(N) # define __LOCALE_PARAM # define __LOCALE_ARG # define __LOCALE_PTR

since posix_openpt lives in getpt.c it has to stay there unconditionally.

Fixes compilation error for defined UCLIBC_HAS_PTY && !defined UNIX98PTY_ONLY which need both __libc_ptyname1 and __libc_ptyname2 for ptsname_r().
2008-06-07- UCLIBC_HAS_GETPT pulls in getpt.Bernhard Reutner-Fischer
- ptsname_r depends on UCLIBC_HAS_PTY just like ptsname()
2008-06-04This fixes a problem with the move of libc_hidden_proto to string.h.Bernd Schmidt
The obsolete functions bcopy, index, etc. are not supposed to be used within uClibc itself. Hence, there is no libc_hidden_def for them, but the previous patch did not just move libc_hidden_protos, it also added new ones for the legacy functions. As a result, programs which use these functions can no longer link with uClibc. This fixes it by removing the unnecessary libc_hidden_protos. I've also removed all inclusions of <strings.h> from uClibc source files: since we define _GNU_SOURCE, it is sufficient to include <string.h>. We then do not need to duplicate the libc_hidden_proto block in <strings.h>.
2008-06-03- adds several config-options to allow for turning off certain featuresBernhard Reutner-Fischer
