- Fix for possible unset uid/gid in toproto
- Fix for default mtree style
- Update libelf
- Importing libexecinfo
- Resynchronize GCC, mpc, gmp, mpfr
- build.sh: Replace params with show-params.
This has been done as the make target has been renamed in the same
way, while a new target named params has been added. This new
target generates a file containing all the parameters, instead of
printing it on the console.
- Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
get getservbyport() out of the inner loop

|
|
* The magic number number identifies the jmp_buf and
|
|
* how the buffer was created as well as providing
|
|
* a sanity check
|
|
*
|
|
* A side note I should mention - Please do not tamper
|
|
* with the floating point fields. While they are
|
|
* always saved and restored at the moment this cannot
|
|
* be garenteed especially if the compiler happens
|
|
* to be generating soft-float code so no fp
|
|
* registers will be used.
|
|
*
|
|
* Whilst this can be seen an encouraging people to
|
|
* use the setjmp buffer in this way I think that it
|
|
* is for the best then if changes occur compiles will
|
|
* break rather than just having new builds falling over
|
|
* mysteriously.
