Comment (by kencu):

 Oh, these python ports are hard to manipulate.

 Adding legacysupport does nothing, as it is not used even if added:

 {{{
 usr/bin/gcc-4.2 -fno-strict-aliasing -Wsign-compare -fno-common -dynamic
 -DNDEBUG -g -fwrapv -O3 -Wall -pipe -Os -arch i386 -isysroot/
 -DHAVE_STDINT_H -DPYCRYPTO_LITTLE_ENDIAN -DSYS_BITS=32 -DLTC_NO_ASM
 -DHAVE_EMMINTRIN_H -DUSE_SSE2 -DGCC_REALIGN
 -I/opt/local/Library/Frameworks/Python.framework/Versions/3.10/include/python3.10
 -c src/raw_ocb.c -o build/temp.macosx-10.5-i386-cpython-310/src/raw_ocb.o
 -msse2
 }}}

 forcing gcc7 does fix the c99 errors, but the aligned memory issues still
 happen.

 Perhaps we have to use the compiler wrapper PortGroup to get these python
 ports to obey the extra CFLAGS and LDFLAGS? Let me see...
