Trouble with too many '-W' flags from ./configure

[Wei-keng Liao]

Hi, Giovanni,

Thanks for reporting this issue. This option of enabling strict is intended for GNU compiler only.
I have changed configure.in accordingly in r1207. The default is disable-strict.

I have encountered trouble with the PGI compiler not successfully building due to it not gracefully ignoring the plethora of "-W" flags that are set in the "configure.in" file around lines 80-82.  From my understanding of Autotools, that modification of the CFLAGS variable shouldn't even be happening if I pass the "--disable-strict" flag to the "./configure".  What I have in my ./configure invocation is:

I'm guessing PGI is just picky, and I'll submit a bug report to them as well.  However, there is something not quite right here
