The GNU Project has released version 4.0.4 of GCC, the GNU Compiler Collection. GCC contains frontends for C, C++, Objective C, Chill, Fortran, Ada, and Java as well as libraries for these languages. GCC's Java is a clean room implementation that doesn't use any Sun code, so it doesn't always exactly match Sun release versions, but this is roughly at the Java 1.4 level with some omissions. 4.0.4 is a bug fix release. "The 4.0.4 release is provided for those that require a high degree of binary compatibility with previous 4.0.x releases. For most users, the GCC team recommends that version 4.1.1 or later be used instead."
