Have prte_version.h generated via AC_CONFIG_HEADERS, not AC_CONFIG_FILES. This properly quotes strings (which technically doesn't matter here since prte_version.h doesn't include any strings) and also won't overwrite the resulting .h file if it hasn't changed. NOTE: This is a fix for the original commit that brought in this functionality (4da431a) which broke in at least some Linux environments. Apparently, AC_CONFIG_HEADERS -- unlike AC_CONFIG_FILES -- does not like extra newlines at the beginning or end of the file list parameter in at least some Linux environments (although it seems to work find on macOS). Shrug! Signed-off-by: Jeff Squyres <[email protected]> (cherry picked from commit b7196af)
