std::abs(int) requires mathieeedoubbas.library

[claudeha]

Many thanks for your work on amiga-gcc.

I'm targetting 68000 without FPU (currently 2.04, possibly 1.3 later) and aiming for minimal dependencies. This short program requires mathieeedoubbas.library for some reason I don't understand:

#include <cmath>

int main(int argc, char **argv)
{
  (void) argv;
  return std::abs(argc);
}

Writing my own abs replacement with x < 0 ? -x : x works fine without needing the library (INT_MIN is an edge case that I don't really care about in my situation).

I check needed libraries by strings ./binary | grep library.

Then don't use c++, or at least don't use std:: ... this pulls in a ton of dependencies... ... and use -noixemul the default newlib also is not minimal.

__gnu_cxx::__enable_if<std::__is_integer<int>::__value, double>::__type std::abs<int>(int)

uses ___floatsidf which needs tha math lib^^

Don't worry, the only std I'm using are abs calloc fopen free fseek fwrite malloc max memset min and I should be able to replace the FILE with dos.library calls, the memory with exec.library calls, and the rest are easy.
