By default, the compiler generates executable file(s) of the input file(s) and performs the following actions:
Searches for all files, including library files, in the current directory
Searches for any library files in directories specified by the LIB variable, if they are not found in the current directory.
Passes options designated for linking as well as user-defined libraries to the linker
Displays error and warning messages
Supports the extended ANSI standard for the Fortran language.
Performs default settings and optimizations using options summarized in the Deafult Behavior of the Compiler Options section.
For IA-32 applications, the compiler uses use -tpp6 option to optimize the code for the Pentium ProŽ, PentiumŽ II, and Pentium III processors.
For unspecified options, the compiler uses default settings or takes no action. If the compiler cannot process a command-line option, that option is passed to the linker.
