Hi,
Trying to build boost libraries I have following failure when issuing
following command under cygwin 64 on Windows 7 (64bits 6Go RAM):
"g++" -x assembler-with-cpp -O3 -finline-functions -Wno-inline -Wall
-DBOOST_ALL_NO_LIB=1 -DBOOST_CONTEXT_SOURCE -DNDEBUG -I"." -c -o
"bin.v2/libs/context/build/gcc-4.8.2/release/link-static/asm/make_x86_64_sysv_elf_gas.o"
"libs/context/src/asm/make_x86_64_sysv_elf_gas.S"
libs/context/src/asm/make_x86_64_sysv_elf_gas.S: Messages de l'assembleur:
libs/context/src/asm/make_x86_64_sysv_elf_gas.S:43: Avertissement: .type

libs/context/src/asm/make_x86_64_sysv_elf_gas.S:76: Erreur: rebut à la

Could you please tell me what I am doing wrong ?
Regards
assembler code (see attached file):
