Re: detection and support of OpenMP

[Steven G. Johnson]

Sorry I came late to this discussion, but why not use something more like:

   http://autoconf-archive.cryp.to/ax_openmp.html

It's much shorter than the currently proposed macro, and doesn't have 
the hackery of testing for compiler "brand" in order to get the 
flag---it just tries all the known flags until it finds one that works. 
 This is much more in the spirit of autoconf, and much more likely to 
work with new compilers that come along.

The autoconf-archive macro is also reasonably well tested, having been 
used successfully with FFTW for a number of years now.  The only times 
people have reported failures was when it was missing flags for some 
compiler, but all of these cases I am aware of have been rectified in 
the current posted macro.
