Issue: dev-tex/rtf2latex2e-2.2.3 fails to compile with -fno-common.
Discovered on: amd64 (internal ref: seden_tinderbox)

NOTE:
This machine uses GCC-11: https://gcc.gnu.org/gcc-11/porting_to.html
To reproduce this issue you may want to set CFLAGS="${CFLAGS} -fno-common" or compile it with gcc-10 that enables -fno-common by default.
