Here's the patch. Also 2 new source files:
- pystrtod.h goes to Include/
- pystrtod.c goes to Python/
The next step is to ask glib authors for permission to relicense the
code. Also, the locale module should be changed, to allow LC_NUMERIC to
be changed, etc.
Regards.

/**
* g_ascii_strtod:
* @nptr: the string to convert to a numeric value.
* @endptr: if non-%NULL, it returns the character after
* the last character used in the conversion.
*
* Converts a string to a #gdouble value.
* This function behaves like the standard strtod() function
* does in the C locale. It does this without actually
* changing the current locale, since that would not be
* thread-safe.
*
* This function is typically used when reading configuration
* files or other non-user input that should be locale independent.
* To handle input from the user you should normally use the
* locale-sensitive system strtod() function.
*
* To convert from a #gdouble to a string in a locale-insensitive
* way, use g_ascii_dtostr().
*
* If the correct value would cause overflow, plus or minus %HUGE_VAL
* is returned (according to the sign of the value), and %ERANGE is
* stored in %errno. If the correct value would cause underflow,
* zero is returned and %ERANGE is stored in %errno.
*
* This function resets %errno before calling strtod() so that
* you can reliably detect overflow and underflow.
*
* Return value: the #gdouble value.
