[Devel:Compiler] TCC package (Tiny C Compiler)

[Edit:] I had to add a couple lines to the PKGBUILD to force it to use the right library paths

Tiny C is a fast lightweight C compiler and interpreter (allowing C to be used as a scripting language).

PKGBUILD:

# Contributor: Chris Osgood <archlinux at functionalfuture.com>
pkgname=tcc
pkgver=0.9.20
pkgrel=2
pkgdesc="Tiny C Compiler (TCC) is a lightweight C compiler that can also interpret C as a scripting language."
url="http://fabrice.bellard.free.fr/tcc"
license="LGPL"
depends=( )
makedepends=('perl')
source=(http://fabrice.bellard.free.fr/$pkgname/$pkgname-$pkgver.tar.gz)
md5sums=('c883b88e874a9bb9163eb14dc43b178c')

build() {
  cd $startdir/src/$pkgname-$pkgver
  patch -Np1 -i ../../tcc.patch
  ./configure --prefix=$startdir/pkg/usr
  echo '#undef CONFIG_TCC_LIBDIR' >> config.h
  echo '#define CONFIG_TCC_LIBDIR "/usr/lib"' >> config.h
  make || return 1
  mkdir -p $startdir/pkg/usr/bin
  mkdir -p $startdir/pkg/usr/include
  mkdir -p $startdir/pkg/usr/lib
  mkdir -p $startdir/pkg/usr/man/man1
  make install
}

tcc.patch (My patch that makes it compilable with GCC 3.4):
