Subject: Minor refinements:
X-Git-Tag: svn/VALGRIND_3_5_0~1036
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a0bf8f8271bb56cd78b24b66d29b728cc63e414c;p=thirdparty%2Fvalgrind.git

Minor refinements:

* h_main.c: handle a few more syscalls

* exp-ptrcheck.supp: ignore errors in glibc's getenv -- is highly optimised

* pc_common.c: fix small error in error message printing

--> 3_4_BRANCH
