2015-02-03make execvp continue PATH search on EACCES rather than issuing an errrorRich Felker1-1/+4
the specification for execvp itself is unclear as to whether encountering a file that cannot be executed due to EACCES during the PATH search is a mandatory error condition; however, XBD 8.3's specification of the PATH environment variable clarifies that the search continues until a file with "appropriate execution permissions" is found. since it seems undesirable/erroneous to report ENOENT rather than EACCES when an early path element has a non-executable file and all later path elements lack any file by the requested name, the new code stores a flag indicating that EACCES was seen and sets errno back to EACCES in this case.

2013-02-17consistently use the internal name __environ for environRich Felker1-2/+2
patch by Jens Gustedt. previously, the intended policy was to use __environ in code that must conform to the ISO C namespace requirements, and environ elsewhere. this policy was not followed in practice anyway, making things confusing. on top of that, Jens reported that certain combinations of link-time optimization options were breaking with the inconsistent references; this seems to be a compiler or linker bug, but having it go away is a nice side effect of the changes made here.
