[Pkg-netsim-devel] Bug#689424: Use of nested functions in configure check

[Michael Tautschnig]

Package: ns2
Version: 2.35+dfsg-1

conf/configure.in.nse uses AC_TRY_COMPILE to detect header files. The second
argument of this macro is supposed to be a function body, but this
configure.in.nse includes int main() { <actual body> }, resulting in nested
functions.

This is accepted by GCC, but other compilers (including CLANG) reject this GCC
extension.

Best,
Michael
