Please correct me if I'm wrong. To my knowledge, gcc is just a compiler. 
It supports language-related features, like the 'restrict' keyword. 
Support for features related to HAVE_ALLOCA or HAVE_TMPFILE are 
supported by the underlying runtime (libc?), which is a separate 
package/tool. Different platforms (DJGPP, MinGW, Cygwin,...) may have 
the same compiler (the same version of gcc), but really different 
runtime support.

Below is a detailed step-by-step trace of my trial-and-error procedure 
to build gawk on MinGW alone (now without MSYS), on Windows XP. It's a 
looong post, but you have requested it :-)

Should I try a different line of action?

-----------------------------------------
Building gawk-3.1.5g (3.1.6beta) on MinGW
-----------------------------------------
2007-06-02, Windows XP


1.- Do a fresh MinGW manual install

- Download and uncompress
binutils-2.17.50-20060824-1.tar.gz
gcc-core-3.4.2-20040916-1.tar.gz
gcc-g++-3.4.2-20040916-1.tar.gz
mingw32-make-3.81-2.tar.gz
mingw-runtime-3.12.tar.gz
w32api-3.9.tar.gz

--- ( y Establecer path mínimo
--- 
PATH=c:\temp\mingw\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem 
)


2.- Copy files  from ./pc to source's root, as stated, and invoke 'make 
mingw32'
(Well, there is no 'make'. Just 'mingw32-make')
C:\Temp\mingw\bin>mingw32-make.exe --version
GNU Make 3.81

3.- Add option -std=c99 in line 193 of Makefile (attempt to get support 
for 'restrict')

4.- Restore the original Makefile (from ./pc). Add '#define restrict 
/*nothing*/' at the end of config.h and remake
