* fix off-by-one bug in siglongjmp that caused unpredictable behaviorRich Felker2011-08-051-1/+1
| | | | | | | | | | if saved, signal mask would not be restored unless some low signals were masked. if not saved, signal mask could be wrongly restored to uninitialized values. in any, wrong mask would be restored. i believe this function was written for a very old version of the jmp_buf structure which did not contain a final 0 field for compatibility with siglongjmp, and never updated...
* fix all implicit conversion between signed/unsigned pointersRich Felker2011-03-251-1/+1
| | | | | | | sadly the C language does not specify any such implicit conversion, so this is not a matter of just fixing warnings (as gcc treats it) but actual errors. i would like to revisit a number of these changes and possibly revise the types used to reduce the number of casts required.
* initial check-in, version 0.5.0 v0.5.0Rich Felker2011-02-121-0/+12
