As discussed on IRC, this adds a couple more checks in the customization setup for git. If the variables user.name and user.email are not set anywhere in the git config hierarchy, we set some local values. We always ask about the values we detect and if the user gives an answer that is new, we save that in the local config: this gives the opportunity to use different values to those configured for the global space. Also cleaned up a couple of minor niggles, such as using $(cmd) rather than `cmd` for subshells and some quoting issues when using eval. * gcc-git-customization.sh: Check that user.name and user.email are set. Use $(cmd) instead of `cmd`. Fix variable quoting when using eval.
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
