Subject: Fix bootstrap.bat for bootstrapping on Windows
X-Git-Tag: 4.3.90~29
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=62da1c45e51f90892dd785fbdd42aeff769defb6;p=thirdparty%2Fmake.git

Fix bootstrap.bat for bootstrapping on Windows

* README.git: Clarify that these methods are lightly tested.
* build_w32.bat: Don't support any config step: fail if not completed.
Move the config steps into bootstrap.bat.  Don't print compile lines
by default and add a --verbose option to show them.
* bootstrap.bat: Ensure we have curl and sed before we do anything.
Pull the latest necessary files from gnulib.  Create a convert.sed
script that can update the various template files, and update
Basic.mk, config.h.W32, and gmk-default.h.
* tests/run_make_tests.pl: Remove CRLF rather than using chop.  If we
run perl in Git for Bash it seems to handle newlines differently.
* tests/scripts/features/temp_stdin: Remove the make copy and close
STDIN so we can delete the temp file on Windows.
* .gitignore: Ignore the convert.sed script.
