I'm trying to compile luatex with --host=x86_64-w64-mingw32 --build=x86_64-linux-gnu (use a fixed font to see the error)

In file included from ../../../source/texk/web2c/__luatexdir/luafontloader/__fontforge/Unicode/char.c:29:0: /media/LaCie/opt/mingw-w64-__bin_x86_64-linux_20121031/x86___64-w64-mingw32/include/ctype.__h:102:23: error: expected ‘)’ before ‘_C’ _CRTIMP int __cdecl isalpha(int _C);

It looks like 'isalpha' is defined as a macro at this point already, making the declaration fail. Does that help?

yes, because source/texk/web2c/luatexdir/luafontloader/fontforge/inc/utype.h has #define isalpha(ch) (____utype[(ch)+1]&(____L|____U|____TITLE|____AL))

but why I have this error only with x86_64-w64-mingw32?

Either the 32bit version probably defines the CRT version differently, e.g., you would probably not get the error with: _CRTIMP int __cdecl isalpha(int) Or the win32 headers do not load internally. One way to test what is going on is running gcc -E to look at the preprocessed output, and another one is to run strace -f on the gcc run to see which files are loaded. Best wishes, Taco
