Summary: atoll should be defined even when strict ansi is enabled
Initial Comment:
When -std=c99 flag is invoked gcc enables __STRICT_ANSI__ and this hides the
definition of atoll() and related functions (see stdlib.h) but atoll() and
related functions like strtoll is part of C99 standard and should be enabled
even if __STRICT_ANSI__ is enabled.

I agree it should be invisible and it should be provided by a library. So,
your solution looks fine.

Hmm.
When I look deeper, there are two possible solutions.
1. The src/mingw/include/stdlib.h contains a definition for an inline
version of atoll.
This could be moved to a place where it remains visible, as Ismail
suggests.
2. There's also an implementation in src/mingw/mingwex/atoll.c .
The build can be tweaked to include it in libmingwex.a .
They call the same function (_atoi64) to do the job.
I feel like doing both, they should not be incompatible and this would
catch cases where the inline function is missed.
Opinions ?

This might be due to their linker flags, they use:
arm-mingw32ce-gcc -shared -Wl,--output-def,libavformat/avformat-52.def
-Wl,--out-implib,libavformat/libavformat.dll.a
-Wl,--enable-runtime-pseudo-reloc -Wl,--enable-auto-image-base

Message:
When compiling ffmpeg with networking support I get the following error:
libavformat/http.o:http.c:(.text+0x640): relocation truncated to fit:
ARM_26 against undefined symbol `atoll'
File is compiled with the following flags:
arm-mingw32ce-gcc -DHAVE_AV_CONFIG_H -I. -I"/root/ffmpeg" -D_ISOC99_SOURCE
-D_POSIX_C_SOURCE=200112 -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE
-I/opt/mingw32ce/include -march=armv4t -std=c99 -fno-common
-fomit-frame-pointer -Wdeclaration-after-statement -Wall -Wno-switch
-Wdisabled-optimization -Wpointer-arith -Wredundant-decls -Wno-pointer-sign
-Wcast-qual -Wwrite-strings -Wundef -O3 -fno-math-errno -fno-tree-vectorize
-c -o libavformat/http.o libavformat/http.c
So I thought it must be __STRICT_ANSI__ breaking atoll.

Message:
For which functions exactly should this be changed ?
I find references to atoll being added, and strtoll.
But strtoll looks right in stdlib.h, even though you mention it.
Maybe only atoll needs changing ?
