37d88e4125 Don't confuse suffixed hexadecimal with floating-point 
1e30 is a floating-point constant, but 1e30h is not.  The scanner
won't know that until it sees the "h", so make sure we keep enough
state to be able to distinguish "1e30" (a possible hex constant) from
"1.e30", "1e+30" or "1.0" (unabiguously floating-point.)

2ef4aac272 Allow underscores in numbers; better detection of FP 
- Allow underscores as group separators in numbers, for example:
  0x1234_5678 is now a legal number.  The underscore is just ignored,
  it adds no meaning.
- Recognize dotless floating-point numbers, such as "1e30".  This
  entails distinguishing hexadecimal numbers in the scanner, since
  e.g. 0x1e30 is a perfectly legitimate hex constant.

8088815922 configure: Undefine __STRICT_ANSI__ for mingw's benefit 
mingw makes a bunch of prototypes unavailable if __STRICT_ANSI__ is
defined.  However, they are still detected by configure, which causes
us pain.

fab3a6c9de Floating-point warning fixes; fix round-to-overflow 
Actually generate the appropriate floating-point warnings, and only
one per assembly, pretty please.

Correct the round-to-overflow condition; as written all numbers with a
positive exponent were considered overflows!

Refactor the floating-point formatting code so that the 80-bit format
can be supported with common code.  This fixes 80-bit denorms as a
side effect; the shift value in 80-bit denorms was completely wrong.

214f549c5c New floating-point conversion routines 
Substitute in nasm64developer's "acfloat4" routine.  This
floating-point conversion routine is not perfect (it gets a fair
number of LSB errors), but the old NASM code was just plain broken.
nasm64developer's code at least gets within ±1 LSB.

70a5d14b89 autoconf: drop AC_USE_SYSTEM_EXTENSIONS to support autoconf 2.59

little too new, apparently.  Unless we have a specific reason to
include it, don't.

70055964fc Additional uses of bool and enum

54901e1785 preproc.c: MMacro.in_progress is not a boolean 
Per the comment:

 * In a MMacro describing a `%rep' block, the `in_progress' field
 * isn't merely boolean, but gives the number of repeats left to
 * run.

This fixes the "global" directive not getting recognized, since it
repeats over all its arguments.

d119ce6f9a saa_fread/fwrite: when seeking, must set [rw]ptr as well

6867acc18e Use the compiler-provided booleans if available, otherwise emulate 
Both C and C++ have "bool", "true" and "false" in lower case; C
requires <stdbool.h> for this, in C++ it is an inherent type built
into the compiler.  Use those instead of the old macros; emulate with
a simple typedef enum if unavailable.
