are using Purify with libffi. Only use this switch when using
Purify, as it will slow down the library.
It's also possible to build libffi on Windows platforms with
Microsoft's Visual C++ compiler. In this case, use the msvcc.sh
wrapper script during configuration like so:
path/to/configure --enable-shared --enable-static \
CC=path/to/msvcc.sh LD=link \
CPP=\"cl -nologo -EP\"
Configure has many other options. Use "configure --help" to see them all.
Once configure has finished, type "make". Note that you must be using
