Subject: [scan-build] Log compiler invocation to stderr, not stdout.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=98137aa8c5c95356454610d88cae079602ca2bec;p=clang

[scan-build] Log compiler invocation to stderr, not stdout.

This is important for preprocessing steps, which may output to stdout.

Also, change ENV accesses using barewords to use string keys instead.
