Compatibility notice 1. Module files: The version of the module files (.mod) has been incremented. 2. For free-form source files, -Werror=line-truncation is now enabled by defau note that comments exceeding the line length are not diagnosed. For fixed-form source code, the same warning is available but turned off by default, such that excess characters are ignored. (-ffree-line-length-n and -ffixed-line-length-n can be used to modify the default line length of 132 and 72 columns, respectively.) 3. The -Wtabs option is now more sensible: with -Wtabs the compiler warns if it encounters tabs and with -Wno-tabs this warning is turned off. Before, -Wno-tabs warned and -Wtabs turned off the warning. As before, the warning is also enabled via -Wall, -pedantic and the f95, f2003, f2008 and f2008ts options of-std=. OpenMP 4.0 is now also fully implemented in gfortran (this feature has been backported to GCC 4.9.1, except for actual offloading).
