Hi hackers,
Another small patch for Windows. This one fixes a symbol visibility
problem when building CHICKEN on Cygwin (64-bit), where the following
currently occurs:
./chicken-boot-stage1.exe posixunix.scm -optimize-level 2 -include-path .
-include-path ./ -inline -ignore-repository -feature chicken-bootstrap
-no-warnings -specialize -types ./types.db -explicit-use -no-trace
-output-file posixunix.c
gcc -fno-strict-aliasing -fwrapv -DHAVE_CHICKEN_CONFIG_H -DC_ENABLE_PTABLES
-c -Os -fomit-frame-pointer -DC_BUILDING_LIBCHICKEN posixunix.c -o
posixunix-static.o -I. -I./
posixunix.c: In function `stub1783':
posixunix.c:401:10: warning: implicit declaration of function `strptime'
[-Wimplicit-function-declaration]
(strptime(C_c_string(s), C_c_string(f), ((struct tm *)(stm))) ?
C_tm_get((v), (stm)) : C_SCHEME_FALSE)
^
posixunix.c:840:14: note: in expansion of macro `C_strptime'
C_r=((C_word)C_strptime(t0,t1,t2,t3));
^
After some reading, defining _XOPEN_SOURCE seems to be the correct thing
to do in general, as well.
Cheers,
Evan
