what if you try this on that debian host ? i dont have gcc-3.3.4 installed, but this works with gcc-3.3.3 and gcc-3.4.0: echo 'int main(){}' > test.c gcc -Wdeclaration-after-statement test.c
Here are the results on the debian machine: ~$ echo 'int main(){}' > test.c ~$ gcc -Wdeclaration-after-statement test.c cc1: error: unrecognized option `-Wdeclaration-after-statement' ~$ Compilation succeeds on the gentoo machine.
-Wdeclaration-after-statement is non-standard for gcc-3.3.x ... it is introduced by our branch updates in the gcc-3.3.x ebuilds ... that is why the debian box doesnt support it the flag itself is added by the kernel Makefile ... it detects that the host machine (the gentoo box) supports the flag and thus adds it into CFLAGS for you ... i would just `env FEATURES=-distcc emerge svgalib` and move on
