## Shared-library variant: the following rule works on Linux

## must appear in the CFLAGS assignment when making libf2c.so.
## Under Solaris, use -Kpic in CFLAGS and use "ld -G" instead
## of "$(CC) -shared".
## For MacOSX 10.4 and 10.5 (and perhaps other versions >= 10.3), use
## "MACOSX_DEPLOYMENT_TARGET=10.3 libtool -dynamic -undefined dynamic_lookup -single_module"
## instead of "$(CC) -shared", and when running programs linked against libf2c.so,
## arrange for $DYLD_LIBRARY_PATH to include the directory containing libf2c.so.
