libffcall1-dev 1.10-3 (amd64 binary) in ubuntu feisty

 This is a collection of four libraries which can be used to build
 foreign function call interfaces in embedded interpreters.
 .
 The four packages are:
 .
    avcall - calling C functions with variable arguments
 .
    vacall - C functions accepting variable argument prototypes
 .
    trampoline - closures as first-class C functions
 .
    callback - closures with variable arguments as first-class C functions
               (a reentrant combination of vacall and trampoline)
