Hello Wei-Keng,<br>
<br>
Building PnetCDF 1.12.3 with AOCC compilers, I found that<br>
libamdlm is linked after libm ('-lm -lamdlibm') instead of<br>
before as it should be; so far I have not found any way to<br>
change this.  If I set LIBS='-lamdlibm' and configure, both<br>
FCLIBS and FLIBS in the resulting Makefile are assigned<br>
