UWIN: UWIN 4.2 (2007-12-11 build)
MinGW: 3.2.0
The following trivial program fails to compile:
/d/uwin/site/local> print $PACKAGE_cc
/D/MinGW
/d/uwin/site/local> cc -V
/D/MinGW
/d/uwin/site/local> cat h.c
#include <stdio.h>
main()
{
printf( "Done" );
}
/d/uwin/site/local> cc -o h h.c
cpp: "/D/MinGW/lib/gcc/mingw32/3.4.2/include/stdarg.h", line 55:
warning: va_copy redefined
In file included from /usr/include/ast/ast_std.h:327,
from /usr/include/ast/ast_stdio.h:103,
from /usr/include/stdio.h:2,
from h.c:2,
from h.c:2:
/usr/include/ast/ast_map.h:107: error: conflicting types for 'strtold'
/D/MinGW/include/stdlib.h:315: error: previous declaration of 'strtold'

/usr/include/ast/ast_map.h:107: error: conflicting types for 'strtold'
/D/MinGW/include/stdlib.h:315: error: previous declaration of 'strtold'
was here
/d/uwin/site/local>
Now looking in ast_map.h around line 107 showed:
106 #ifndef _ISOC99_SOURCE
107 extern __MANGLE__ _ast_fltmax_t strtold __PROTO__((const char*,
char**));
108 #endif
Moreover the only references to the symbol _ISOC99_SOURCE were in
ast/ast_map.h and ast/ast_standards.h in all of the files under
/usr/include. The ast_standards.h file merely sets this symbol (along
with several others).
When I included it manually, all was fine:
/d/uwin/site/local> cat h.c
#include <ast/ast_standards.h>
#include <stdio.h>
main()
{
printf( "Done\n" );
}
/d/uwin/site/local> cc -o h h.c
cpp: "/D/MinGW/lib/gcc/mingw32/3.4.2/include/stdarg.h", line 55:
warning: va_copy redefined
/d/uwin/site/local> ./h
Done
/d/uwin/site/local>
It seems that all that's needed is to introduce a #include
ast_standards.h directive into ast_map.h.
