Several configure tests write integer result values to files and then do something like foo=$(cat conftestval). However, if the conftestval file contains whitespace around the integer value (e.g., if conftestval was written by a Fortran test code), then $foo will still contain that whitespace, too -- which then propagates throughout the configury and elsewhere. This commit uses xargs to strip off the whitespace. There's really only one place where this is happening that is a problem, but let's do it in all places where we foo=$(cat conftestval) with integer results, just as a matter of consistency and defensive programming. Thanks to Lisandro Dalcin for raising the issue. Signed-off-by: Jeff Squyres <[email protected]>
