obtained gcc-4.6.4.tar.bz2 from upstream website;upstream

verified gcc-4.6.4.tar.bz2.sig;
imported gcc-4.6.4 source tree from verified upstream tarball.

downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.

if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective
files in the upstream repository.

+dnl @synopsis AC_PROG_JAVAC
+dnl
+dnl AC_PROG_JAVAC tests an existing Java compiler. It uses the
+dnl environment variable JAVAC then tests in sequence various common
+dnl Java compilers. For political reasons, it starts with the free
+dnl ones.
+dnl
+dnl If you want to force a specific compiler:
+dnl
+dnl - at the configure.in level, set JAVAC=yourcompiler before calling
+dnl AC_PROG_JAVAC
+dnl
+dnl - at the configure level, setenv JAVAC
+dnl
+dnl You can use the JAVAC variable in your Makefile.in, with @JAVAC@.
+dnl
+dnl *Warning*: its success or failure can depend on a proper setting of
+dnl the CLASSPATH env. variable.
+dnl
+dnl TODO: allow to exclude compilers (rationale: most Java programs
+dnl cannot compile with some compilers like guavac).
+dnl
+dnl Note: This is part of the set of autoconf M4 macros for Java
+dnl programs. It is VERY IMPORTANT that you download the whole set,
+dnl some macros depend on other. Unfortunately, the autoconf archive
+dnl does not support the concept of set of macros, so I had to break it
+dnl for submission. The general documentation, as well as the sample
+dnl configure.in, is included in the AC_PROG_JAVA macro.
