21 | # Update our import of gnulib in the GDB source tree. | |
22 | # | |
23 | # This script assumes that it is being called from the gdb/gnulib | |
24 | # subdirectory, and will verify this before proceeding. | |
25 | # | |
26 | # This script will also make a number of other verifications: | |
27 | # . The gnulib version (it should match $GNULIB_COMMIT_SHA1). | |
28 | # . The correct versions of the auto-tools that are used to | |
29 | # regenerate the various scripts and Makefiles are on the PATH. | |
