- move stlport headers to the c++ directory - add a specific _reactos.h configuration file for stlport - add cerrno to c++ headers - __declspec(nothrow) must be placed before calling convention with msvc. GCC doesn't care. We now use our headers with both msvc and gcc. svn path=/branches/cmake-bringup/; revision=49565

/** rough characterization of compiler and native C library
|
|
For the compiler, it can either support long double or not. If it doesn't, the
|
|
macro _STLP_NO_LONG_DOUBLE is not defined and we don't define any long double
|
|
overloads.
|
|
For the native C library the question is whether it has variants with an 'f'
|
|
suffix (for float as opposed to double) or an 'l' suffix (for long double). If
|
|
the float variants are missing, _STLP_NO_VENDOR_MATH_F is defined, when the
|
|
long double variants are missing, _STLP_NO_VENDOR_MATH_L is defined. Of course
|
|
the latter doesn't make sense anyway when the compiler already has no long
|
|
double support.
|
|
|
|
Those two traits determine a) which overloads get defined and b) how they are
|
|
defined.
|
|
|
|
Meaning of suffixes:
|
|
"" : function returning and taking a float_type
|
|
"2" : function returning a float_type and taking to float_types
|
|
"2P" : function returning a float_type and taking a float_type and a float_type*
|
|
"2PI": function returning a float_type and taking a float_type and an int*
|
|
"2I" : function returning a float_type and taking a float_Type and an int
