[svn-r13373] Problem:
Daily tests failed on smirom with g95
Solution:
Our algorithm to detect size of Fortran real had a flaw: it didn't work
when size of integer was bigger than real; fixed
Platforms tested:
smirom with g95 and -r8, -i4, -r8 -i4 combinations of compilation flags to set
different sizes of integers and real
smirom with pgf90 using -i8 flag and without it
linew in 32 and 64-bit modes
